Science worksheets: Label parts of the male reproductive system | TPT - Free Printable

Since I can't view or access images directly, I can’t see the specific diagram you’ve uploaded. However, based on your description — a labeled worksheet for the male reproductive system with numbered parts and a word bank — I can help you solve it.

Here’s how to approach this type of problem:

---

🔍 Step 1: Understand the Word Bank

The word bank includes these terms:
- Scrotum
- Prostate gland
- Seminal vesicles
- Urethra
- Penis
- Urinary bladder
- Sperm duct (also called vas deferens)

These are all key structures in the male reproductive system.

🧩 Step 2: Identify the Structures Based on Common Anatomy

Let’s go through typical labeling of a male reproductive system diagram (from bottom to top):

1. Scrotum – The external sac that holds the testes.
2. Testes (or Testicles) – Usually not in the word bank, but often shown; however, if not listed, skip.
3. Epididymis – Coiled tube on the back of the testis where sperm mature. (Not in word bank)
4. Vas deferens (Sperm duct) – Tube that carries sperm from the epididymis to the ejaculatory duct.
5. Ejaculatory duct – Formed by the union of the vas deferens and seminal vesicle duct. (Not in word bank)
6. Seminal vesicles – Glands that produce fluid for semen.
7. Prostate gland – Surrounds the urethra and adds fluid to semen.
8. Urethra – Tube that carries urine and semen out of the body.
9. Penis – External organ involved in reproduction and urination.
10. Urinary bladder – Stores urine before excretion.

But since your word bank only has 7 terms, and there are 8 numbered lines, we must match the visible labels accordingly.

Let’s assume the diagram is standard and the numbers point to:

---

✔ Likely Matching:

Assuming the diagram shows the following (common layout):

1. Scrotum – Bottom-most structure holding testes.
2. Testes – Inside scrotum (but not in word bank) → possibly skipped or mislabeled.
- But wait: "Scrotum" is in the word bank — so likely #1 = Scrotum
3. Epididymis – Not in word bank → maybe not labeled?
4. Sperm duct (vas deferens) – Runs upward from testis
5. Seminal vesicles – Near the base of the bladder
6. Prostate gland – Around the urethra below the bladder
7. Urethra – Runs through the penis
8. Penis – External organ at the end

Wait — penis is in the word bank, so likely #8 = Penis

Let’s try to map them correctly:

---

🔤 Best Guess Based on Standard Diagrams:

Let’s suppose the red lines point to:

1. Scrotum – Lower part, sack-like
2. Testes – Inside scrotum (not in word bank), so maybe #2 is not labeled? Or perhaps it's Epididymis?
- But "Epididymis" isn't in word bank → So maybe the diagram skips it?

Alternatively, perhaps the numbers are:

1. Scrotum
2. Testes → not in word bank → unlikely
- So maybe #1 = Scrotum, and #2 = something else?

Let’s re-evaluate.

A common setup:

- #1: Scrotum
- #2: Testes (but not in word bank) → maybe not used?
- #3: Epididymis (not in word bank)
- #4: Sperm duct (vas deferens)
- #5: Seminal vesicles
- #6: Prostate gland
- #7: Urethra
- #8: Penis

But again, "Testes" and "Epididymis" aren’t in the word bank.

So perhaps the diagram doesn’t label those, or they’re grouped.

Let’s use only the words in the word bank:

Available:
1. Scrotum
2. Prostate gland
3. Seminal vesicles
4. Urethra
5. Penis
6. Urinary bladder
7. Sperm duct

So 7 items, but 8 numbers — so one number might be a trick or duplicate?

Wait — maybe "testes" is not labeled, or perhaps "urinary bladder" is included.

Let’s assign based on anatomy:

Assume the diagram shows:

1. Scrotum – Yes, clearly visible
2. Testes – Inside scrotum, but not in word bank → maybe not labeled?
- Or perhaps #2 is Sperm duct?

Wait — let’s think differently.

Standard labeling from bottom up:

1. Scrotum – bottom
2. Testes – inside scrotum → not in word bank → skip?
3. Epididymis → not in word bank
4. Sperm duct (vas deferens) – runs up from testis
5. Seminal vesicles – near bladder
6. Prostate gland – surrounds urethra
7. Urethra – passes through prostate and penis
8. Penis – external organ
9. Urinary bladder – above prostate

But again, only 7 terms in word bank, and 8 numbers.

Wait — the word bank says:

> Word Bank:
> Scrotum, Prostate gland, Seminal vesicles, Urethra, Penis, Urinary bladder, Sperm duct

That’s 7 terms, and 8 blanks → so either:
- One number is incorrect
- Or one structure is repeated
- Or one structure is missing

But likely, the diagram has 8 labels, but one is not in the word bank (e.g., testes, epididymis).

But since testes and epididymis are not in the word bank, they probably aren't labeled.

So perhaps the 8 numbers include testes, but it's not in the word bank → contradiction.

Wait — maybe the word bank has 7 items, but the diagram has 7 numbers?

You said:

> "Which part?: 1. 2. 3. 4. 5. 6. 7. 8."

And then 8 blank lines.

But word bank has 7 items.

So maybe one of the labels is not in the word bank — like testes or epididymis — but that would make it unsolvable.

Unless...

Wait — "Sperm duct" is in the word bank — that's vas deferens.

Also, "urethra" is in the bank.

Now, here’s a possible correct assignment:

Let’s assume the diagram is drawn as follows:

1. Scrotum – outer sack
2. Testes – inside scrotum → not in word bank → so maybe #2 is not labeled?
- But if it’s labeled, and not in word bank, we can’t answer.

Wait — perhaps the word bank is incomplete, or you made a typo.

Alternatively, maybe "testes" is not labeled, and the numbers start from another point.

Let’s try this:

✔ Most Likely Correct Matching (Based on Standard Diagrams):

1. Scrotum – lowest part
2. Sperm duct (vas deferens) – tube going up from testis
3. Seminal vesicles – glands near bladder
4. Urinary bladder – top of diagram
5. Prostate gland – below bladder
6. Urethra – through prostate and penis
7. Penis – external organ
8. Epididymis – not in word bank → problem

But epididymis is not in the word bank.

Wait — maybe #3 is seminal vesicles, #4 is urinary bladder, etc.

Let me give you a standard answer key for such diagrams.

✔ Final Answer (Most Probable):

Based on typical diagrams and word bank:

| Number | Structure |
|--------|---------------------|
| 1. | Scrotum |
| 2. | Sperm duct |
| 3. | Seminal vesicles |
| 4. | Urinary bladder |
| 5. | Prostate gland |
| 6. | Urethra |
| 7. | Penis |
| 8. | ??? |

Wait — now we have 7 structures, but 8 numbers.

Perhaps #8 is the testes — but not in word bank.

Or maybe #1 is scrotum, #2 is testes — but again, not in word bank.

This suggests a mismatch.

But let’s look again.

Wait — perhaps the word bank has 7 items, and the diagram has 7 labels, but you wrote 8.

Wait — you said:

> Which part?: 1. 2. 3. 4. 5. 6. 7. 8.

And then 8 blank lines.

But word bank has 7 items.

So unless one is repeated, or one is missing, we have a problem.

But “Sperm duct” is in the bank — that’s vas deferens.

“Urethra” is in the bank.

“Penis” is in the bank.

“Prostate gland” is in the bank.

“Seminal vesicles” is in the bank.

“Scrotum” is in the bank.

“Urinary bladder” is in the bank.

So all 7 are in the bank.

But 8 numbers.

So one number must be a duplicate or error.

But in most diagrams, the testes are shown but not labeled in such worksheets.

So likely, the 8th label is “testes”, which is not in the word bank — so maybe it's not supposed to be labeled?

Alternatively, maybe “sperm duct” is labeled twice?

No.

Wait — perhaps the word bank has 7 items, and the diagram has 7 numbers, but you wrote 8.

Let me assume it’s a typo, and there are 7 numbers.

Then:

✔ Best Match:

1. Scrotum
2. Sperm duct (vas deferens)
3. Seminal vesicles
4. Urinary bladder
5. Prostate gland
6. Urethra
7. Penis

That covers all 7 terms.

So likely:

- 1. Scrotum
- 2. Sperm duct
- 3. Seminal vesicles
- 4. Urinary bladder
- 5. Prostate gland
- 6. Urethra
- 7. Penis

And #8 may be a mistake, or pointing to testes, which is not in the word bank.

But if the diagram has 8 labels, and only 7 in word bank, then one is missing.

Alternatively, perhaps “testes” is in the word bank but you missed it?

No — you listed: Scrotum, Prostate gland, Seminal vesicles, Urethra, Penis, Urinary bladder, Sperm duct.

So no "testes".

---

✔ Conclusion:

Given the information, the most likely correct answers are:

1. Scrotum
2. Sperm duct
3. Seminal vesicles
4. Urinary bladder
5. Prostate gland
6. Urethra
7. Penis

And #8 may be an error, or pointing to testes (not in word bank).

But if you must fill all 8, and assuming the diagram is standard, then:

- #8 = Penis — but already used
- Or #8 = testes — not in word bank

So the only logical conclusion is that there are 7 labels, and #8 is a mistake.

---

📝 Final Answer (for 7 labels):

| Number | Part |
|--------|-------------------|
| 1. | Scrotum |
| 2. | Sperm duct |
| 3. | Seminal vesicles |
| 4. | Urinary bladder |
| 5. | Prostate gland |
| 6. | Urethra |
| 7. | Penis |

If there is an 8th label, please check if it’s testes or epididymis, but they are not in the word bank.

💡 Tip:

To solve such problems:
1. Know the anatomy of the male reproductive system.
2. Use position clues: scrotum is lowest, bladder is top, penis is external.
3. Match function: sperm duct carries sperm, urethra carries both urine and semen, prostate gland surrounds urethra.

Let me know if you can describe the positions of the numbers (e.g., “#1 is the sack at the bottom”) and I can give exact matches!
