What Are the Parts of the Male Reproductive System? Human Body ... - Free Printable

Let’s go step by step to solve this worksheet about the male reproductive system.

---

Part I: Match terms in Column A with descriptions in Column B

We are matching parts of the male reproductive system (Column A) with their functions or locations (Column B).

Here’s what each term means:

- a. penis → The external organ used for urination and sexual intercourse. It delivers sperm into the female reproductive tract during sex.
- b. scrotum → The sac outside the body that holds the testes. Keeps them cooler than body temperature so sperm can develop properly.
- c. urethra → Tube that carries both urine from the bladder and semen from the reproductive organs out through the penis.
- d. epididymis → Coiled tube on top of each testicle where sperm mature and are stored before ejaculation.
- e. vas deferens → Tube that carries mature sperm from the epididymis to the urethra during ejaculation.
- f. seminal vesicles → Glands that produce fluid (seminal fluid) that mixes with sperm to make semen. This fluid gives sperm energy and helps them move.
- g. prostate gland → Gland below the bladder that adds more fluid to semen. Helps nourish and protect sperm.
- h. bulbourethral glands → Small glands near the base of the penis that release a clear fluid before ejaculation to clean and lubricate the urethra.
- i. testes → Organs inside the scrotum that produce sperm and testosterone (male hormone).

Now let’s match:

1. “portion of duct that holds the testes” → That’s the scrotum → b
2. “duct that carries sperm and urine to the outside of the body” → That’s the urethra → c
3. “region of the male reproductive system that produces sperm” → That’s the testes → i
4. “tube that stores sperm until they mature” → That’s the epididymis → d
5. “collects fluid that mixes sperm” → That’s the seminal vesicles → f

Wait — let’s double-check #5: “collects fluid that mixes sperm” — actually, the seminal vesicles *produce* fluid that mixes with sperm. But looking at Column B, option f says “collects fluid that mixes sperm” — that might be slightly misleading, but among the choices, it’s still best matched to seminal vesicles because they contribute fluid to semen.

Actually, re-reading Column B options:

Looking again at the image text (as described):

Column B:
a. portion of duct that holds the testes
b. duct that carries sperm and urine to the outside of the body
c. region of the male reproductive system that produces sperm
d. tube that stores sperm until they mature
e. collects fluid that mixes sperm

Wait — there’s a mismatch in labeling? Let me reconstruct based on standard knowledge and typical worksheet structure.

Actually, looking carefully at the user’s transcription:

> Column A:
> 1. _______
> 2. _______
> 3. _______
> 4. _______
> 5. _______
>
> Column B:
> a. portion of duct that holds the testes
> b. duct that carries sperm and urine to the outside of the body
> c. region of the male reproductive system that produces sperm
> d. tube that stores sperm until they mature
> e. collects fluid that mixes sperm

And Column A terms are listed as:

From the diagram labels (in Part III), we see:

But wait — in Part I, the terms to match are probably:

Actually, looking back at the original problem statement:

It says:

“Match terms in Column A with its description in Column B. Write only the correct letter in the space provided.”

Then lists:

Column A has numbers 1–5, and Column B has letters a–e.

But then under that, it lists:

“Column A” followed by:

penis
scrotum
urethra
epididymis
vas deferens
seminal vesicles
prostate gland
bulbourethral glands
testes

That seems like too many for just 5 matches.

Ah — I think the actual matching is between the numbered blanks (1–5) and the descriptions (a–e). The list of terms (penis, scrotum, etc.) may be for reference or for later parts.

Wait — no, looking again:

The worksheet says:

“Part I: Match terms in Column A with its description in Column B. Write only the correct letter in the space provided.”

Then it shows:

_______ 1.
_______ 2.
_______ 3.
_______ 4.
_______ 5.

And then:

Column A:
penis
scrotum
urethra
epididymis
vas deferens
seminal vesicles
prostate gland
bulbourethral glands
testes

Column B:
a. portion of duct that holds the testes
b. duct that carries sperm and urine to the outside of the body
c. region of the male reproductive system that produces sperm
d. tube that stores sperm until they mature
e. collects fluid that mixes sperm

This is confusing — there are 9 terms in Column A but only 5 blanks and 5 descriptions in Column B.

I think the intention is that you pick 5 of those terms that match the 5 descriptions.

So let’s match the descriptions to the correct terms:

Description a: “portion of duct that holds the testes” → That’s the scrotum → So blank 1 = scrotum → answer: b? Wait no — Column B is the descriptions labeled a-e, and we write the letter next to the number.

Actually, standard format: You have 5 statements (numbered 1–5) which are descriptions, and you match them to terms in Column A (which are labeled with letters? Or vice versa?)

Looking at the layout:

It says:

“Write only the correct letter in the space provided.”

And then:

_______ 1. [description]
_______ 2. [description]
etc.

And then “Column A” lists terms, “Column B” lists descriptions.

But in the text provided, Column B is listed as:

a. portion of duct that holds the testes
b. duct that carries sperm and urine to the outside of the body
c. region of the male reproductive system that produces sperm
d. tube that stores sperm until they mature
e. collects fluid that mixes sperm

And Column A is the list of terms: penis, scrotum, etc.

But then the blanks are numbered 1–5, and we’re to put a letter (from Column B?) next to each number? That doesn’t make sense.

I think there’s a formatting issue in how the user transcribed it.

Perhaps it’s:

You have 5 descriptions (labeled 1–5), and you match them to terms in Column A (which should be labeled a–i), but in the transcription, Column A is listed without letters.

Alternatively, maybe the "Column A" and "Column B" headers are swapped.

Let me reinterpret based on common worksheets.

Typically, in such matching exercises:

Left column: Terms (with letters)
Right column: Descriptions (with numbers)
Or vice versa.

But here, the user wrote:

“Column A” followed by a list of terms (penis, scrotum, ...)
“Column B” followed by descriptions (a. portion..., b. duct..., etc.)

And then blanks: _______ 1., _______ 2., etc.

With instruction: “Write only the correct letter in the space provided.”

So likely, the descriptions are numbered 1–5, and we match them to the terms in Column A, but Column A terms need to be assigned letters.

But in the text, Column A terms are not lettered.

Perhaps the terms in Column A are meant to be matched to the descriptions in Column B, and we write the letter of the description next to the term? But the blanks are numbered 1–5.

Another possibility: The 5 blanks correspond to 5 specific terms from Column A, and we match them to the 5 descriptions in Column B.

But which 5 terms? Probably the most basic ones.

Looking at the diagram in Part III, it labels parts with letters a-g, but that's separate.

Perhaps for Part I, the intended matches are:

Let’s assume that the 5 descriptions in Column B are to be matched to 5 of the terms in Column A, and we write the letter of the term next to the description number.

But the instruction says: “Write only the correct letter in the space provided.” and the spaces are next to numbers 1–5, which are likely the descriptions.

I think the safest way is to match each description to the correct term, and since the terms are listed, we can assign:

For description 1: “portion of duct that holds the testes” → scrotum
But scrotum is not a duct; it's a sac. "Portion of duct" might be misphrased. Actually, the scrotum is not a duct; it's an external pouch.

Perhaps "portion of duct" refers to something else.

Let’s look at standard definitions:

- Scrotum: holds the testes — matches "portion of duct that holds the testes"? Not really, but closest.

Actually, upon second thought, "portion of duct that holds the testes" is poorly worded. The scrotum is not a duct. Perhaps it's a mistake, and it should be "sac that holds the testes".

In many worksheets, "scrotum" is matched with "holds the testes".

Similarly:

2. “duct that carries sperm and urine to the outside of the body” → urethra

3. “region of the male reproductive system that produces sperm” → testes

4. “tube that stores sperm until they mature” → epididymis

5. “collects fluid that mixes sperm” → seminal vesicles (they produce fluid that mixes with sperm)

So if we assume that the descriptions are numbered 1 to 5, and we need to choose the correct term from Column A for each, but the answer requires writing a letter, perhaps the terms in Column A are implicitly lettered in order.

Let’s list Column A terms in order as given:

1. penis
2. scrotum
3. urethra
4. epididymis
5. vas deferens
6. seminal vesicles
7. prostate gland
8. bulbourethral glands
9. testes

If we assign letters a-i to these in order:

a. penis
b. scrotum
c. urethra
d. epididymis
e. vas deferens
f. seminal vesicles
g. prostate gland
h. bulbourethral glands
i. testes

Then match the descriptions:

Description 1: “portion of duct that holds the testes” → scrotum → b
Description 2: “duct that carries sperm and urine to the outside of the body” → urethra → c
Description 3: “region of the male reproductive system that produces sperm” → testes → i
Description 4: “tube that stores sperm until they mature” → epididymis → d
Description 5: “collects fluid that mixes sperm” → seminal vesicles → f

So answers for Part I:

1. b
2. c
3. i
4. d
5. f

But the worksheet might expect only the letters corresponding to the terms, and since Column B has a-e, perhaps it's the other way around.

I think there's confusion in the transcription.

Perhaps "Column A" is the descriptions, and "Column B" is the terms, but the user wrote it backwards.

Let me check the user's input again:

"Column A:
penis
scrotum
urethra
epididymis
vas deferens
seminal vesicles
prostate gland
bulbourethral glands
testes

Column B:
a. portion of duct that holds the testes
b. duct that carries sperm and urine to the outside of the body
c. region of the male reproductive system that produces sperm
d. tube that stores sperm until they mature
e. collects fluid that mixes sperm"

And then blanks: _______ 1., _______ 2., etc.

With "Write only the correct letter in the space provided."

So likely, the 5 blanks correspond to the 5 descriptions in Column B, and we need to write the letter of the term from Column A that matches.

But Column A terms are not lettered. Unless we assume they are lettered in order as above.

Perhaps in the original worksheet, Column A has letters, but in the text, it's omitted.

To resolve this, I'll assume that the terms in Column A are to be matched to the descriptions in Column B, and for the 5 descriptions, we select the correct term and write its position or letter.

But the instruction is to write the letter, so probably Column A terms have letters.

Given the context, I think the intended matching is:

For each description in Column B (a-e), find the matching term in Column A, but the blanks are for the descriptions numbered 1-5, which are the same as a-e.

Perhaps the "1." corresponds to description a, "2." to b, etc.

That makes sense.

So:

Blank 1: for description a ("portion of duct that holds the testes") → match to scrotum → if scrotum is the second term in Column A, and if we letter Column A as a=penis, b=scrotum, etc., then answer is b.

But let's define:

Assume Column A terms are indexed as:

A1: penis
A2: scrotum
A3: urethra
A4: epididymis
A5: vas deferens
A6: seminal vesicles
A7: prostate gland
A8: bulbourethral glands
A9: testes

Then for description a: "portion of duct that holds the testes" → A2: scrotum → so if we write the index, but the instruction says "letter", so perhaps not.

I recall that in some worksheets, the terms in Column A are labeled with letters, and descriptions with numbers, and you write the letter next to the number.

Here, since Column B has a-e, and blanks are 1-5, likely 1 corresponds to a, 2 to b, etc., and we write the letter of the term from Column A.

But Column A needs letters.

Perhaps the "Column A" list is meant to be read as the terms, and we use their first letter or something, but that's not reliable.

Another idea: perhaps the matching is between the terms and descriptions, and the blanks are for the terms, but the numbering is off.

Let's look at Part II and III for clues.

Part II: Complete the following

1. What is the function of the scrotum?

2. How does the structure of the urethra differ in males and females?

3. Do all human males excrete urine through the penis? Explain your answer.

Part III: Label the diagram with letters a-g, and identify the parts.

Diagram has labels a to g pointing to parts.

From standard anatomy:

In the male reproductive system diagram:

- a: likely seminal vesicle
- b: vas deferens
- c: prostate gland
- d: urethra
- e: penis
- f: testis
- g: epididymis
- h: scrotum (but in the diagram, it might be included)

In the user's description, the diagram has labels a to g, and we need to name them.

Also, in Part III, it says: "Label the parts using the letters a-g. Identify the parts: a. __________ b. __________ etc."

And the diagram is shown with a,b,c,d,e,f,g.

From typical diagrams:

- a: seminal vesicle
- b: vas deferens
- c: prostate gland
- d: urethra
- e: penis
- f: testis
- g: epididymis

Sometimes scrotum is also labeled, but here only a-g are used.

In the user's text, it says "the diagram" with labels a to g, and we need to identify.

Also, in Part I, perhaps the matching is independent.

To simplify, for Part I, I'll provide the matches as per standard knowledge.

Let me state the correct matches:

- "portion of duct that holds the testes" → scrotum (even though "duct" is inaccurate, it's commonly accepted)
- "duct that carries sperm and urine to the outside of the body" → urethra
- "region of the male reproductive system that produces sperm" → testes
- "tube that stores sperm until they mature" → epididymis
- "collects fluid that mixes sperm" → seminal vesicles (they secrete fluid that becomes part of semen)

So for the blanks:

If blank 1 is for "portion of duct that holds the testes", answer is scrotum

But the instruction is to write the letter, so perhaps in the original, the terms have letters.

Since the user didn't provide letters for Column A, I'll assume that for Part I, the answers are the terms themselves, but the format asks for letters.

Perhaps "Column B" is the terms, and "Column A" is the descriptions, but the user swapped them.

Let's swap mentally:

Suppose Column A is the descriptions (a-e), and Column B is the terms (listed as penis, scrotum, etc.).

Then for description a: "portion of duct that holds the testes" → match to scrotum

But still, no letters for terms.

I think the best course is to provide the matches as:

1. scrotum
2. urethra
3. testes
4. epididymis
5. seminal vesicles

And for the letter, since the worksheet likely has the terms lettered, and from the list, if we take the order:

Let's say the terms in Column A are to be considered as:

A: penis
B: scrotum
C: urethra
D: epididymis
E: vas deferens
F: seminal vesicles
G: prostate gland
H: bulbourethral glands
I: testes

Then:

1. "portion of duct that holds the testes" → B (scrotum)
2. "duct that carries sperm and urine to the outside of the body" → C (urethra)
3. "region of the male reproductive system that produces sperm" → I (testes)
4. "tube that stores sperm until they mature" → D (epididymis)
5. "collects fluid that mixes sperm" → F (seminal vesicles)

So answers for Part I: 1.B, 2.C, 3.I, 4.D, 5.F

But since the instruction is to write the letter, and in the blank, it's probably the letter of the term.

For the sake of completing, I'll go with that.

Now Part II:

1. What is the function of the scrotum?

The scrotum is a sac that holds the testes outside the body. Its main function is to keep the testes at a temperature slightly lower than body temperature, which is necessary for sperm production.

2. How does the structure of the urethra differ in males and females?

In males, the urethra is longer and serves two purposes: it carries urine from the bladder and semen from the reproductive organs out through the penis. In females, the urethra is shorter and only carries urine from the bladder to the outside; it is separate from the reproductive system.

3. Do all human males excrete urine through the penis? Explain your answer.

Yes, all human males excrete urine through the penis. The urethra runs through the penis and is the passageway for both urine and semen. When urinating, urine flows from the bladder through the urethra and out the tip of the penis. There are no other exits for urine in males.

Part III: Label the diagram.

From standard male reproductive system diagram:

- a: seminal vesicle (produces fluid for semen)
- b: vas deferens (carries sperm from epididymis to urethra)
- c: prostate gland (adds fluid to semen)
- d: urethra (carries urine and semen out)
- e: penis (external organ for delivery of sperm and urination)
- f: testis (produces sperm and testosterone)
- g: epididymis (stores and matures sperm)

Sometimes the scrotum is labeled, but here only a-g are used, and in the diagram, g is likely epididymis.

In the user's description, the diagram has labels a to g, and we need to identify.

Also, in the text, it says "Identify the parts: a. __________ b. __________ c. __________ d. __________ e. __________ f. __________ g. __________"

So:

a. seminal vesicle
b. vas deferens
c. prostate gland
d. urethra
e. penis
f. testis
g. epididymis

Note: sometimes "testis" is singular, "testes" plural, but in labeling, it's often "testis" for one.

Now, to compile the final answer.

Since the user asked to solve the problem accurately, and provide final answer after reasoning, I'll summarize.

For Part I, assuming the terms are lettered as above:

1. B (scrotum)
2. C (urethra)
3. I (testes)
4. D (epididymis)
5. F (seminal vesicles)

But to match the format, perhaps write the letters.

Since the worksheet might expect the letter from Column B, but that doesn't make sense.

Another interpretation: perhaps "Column A" is the terms, and "Column B" is the descriptions, and for each term in Column A, you match to a description in Column B, but there are 9 terms and 5 descriptions, so only 5 are used.

The blanks are 1-5, so likely for the 5 descriptions, you write the letter of the matching term.

And if we assign letters to Column A terms in order:

Let’s say:

Term 1: penis - A
Term 2: scrotum - B
Term 3: urethra - C
Term 4: epididymis - D
Term 5: vas deferens - E
Term 6: seminal vesicles - F
Term 7: prostate gland - G
Term 8: bulbourethral glands - H
Term 9: testes - I

Then:

Description 1: "portion of duct that holds the testes" -> scrotum -> B
Description 2: "duct that carries sperm and urine to the outside of the body" -> urethra -> C
Description 3: "region of the male reproductive system that produces sperm" -> testes -> I
Description 4: "tube that stores sperm until they mature" -> epididymis -> D
Description 5: "collects fluid that mixes sperm" -> seminal vesicles -> F

So answers for Part I: 1.B, 2.C, 3.I, 4.D, 5.F

For Part II:

1. The scrotum holds the testes and keeps them cool for sperm production.
2. Male urethra is longer and carries both urine and semen; female urethra is shorter and only carries urine.
3. Yes, because the urethra passes through the penis and is the only exit for urine in males.

For Part III:

a. seminal vesicle
b. vas deferens
c. prostate gland
d. urethra
e. penis
f. testis
g. epididymis

Now, for the Final Answer, since the user may want all parts, I'll provide a comprehensive answer.

But the instruction is to provide only the final correct answer after all explanations.

So I'll box the answers for each part.

Final Answer:

Part I:
1. B
2. C
3. I
4. D
5. F

Part II:
1. The scrotum holds the testes and maintains a lower temperature for sperm development.
2. The male urethra is longer and transports both urine and semen, while the female urethra is shorter and only transports urine.
3. Yes, all human males excrete urine through the penis because the urethra, which carries urine, runs through the penis and is the sole exit for urine in the male urinary system.

Part III:
a. seminal vesicle
b. vas deferens
c. prostate gland
d. urethra
e. penis
f. testis
g. epididymis
