Body Systems and Organs Graphic Organizer - Free Printable

Let's solve this diagram step by step. This is a concept map of the human body systems, showing how they are interconnected and what their main functions and components are.

We need to fill in the blanks labeled 1 through 15 based on biological knowledge and the relationships shown in the diagram.

Step-by-step Analysis:

#### 1. Nervous System
- Includes: spinal cord
- So, the other major component of the nervous system is the brain.
- ✔ 1. brain

#### 2. Integumentary System
- Functions to protect tissues
- Includes: sweat glands
- The integumentary system includes the skin, hair, nails, etc.
- ✔ 2. skin

#### 3. Integumentary System
- Includes: sweat glands and ___
- Another major structure in the integumentary system is hair or nails. Since "sweat glands" are listed, likely missing is hair or nails.
- But since it’s connected to "protect tissues", and both hair and nails contribute, but hair is more commonly associated with protection (e.g., eyebrows, eyelashes).
- However, nails are also part of it.
- But let’s look at context — the blank is after "includes", so likely hair or nails.
- But often, hair is listed alongside sweat glands.
- ✔ 3. hair (or possibly nails — but hair is more typical)

Wait — actually, sweat glands and sebaceous glands are common inclusions. But "hair" is also a key component.

But let’s check the flow: “includes” → sweat glands and ___

So likely: hair or nails — but hair is more directly associated with protection.

Alternatively, sebaceous glands? But that’s not typically listed as a major organ.

Actually, standard components: skin, hair, nails, glands (sweat, sebaceous).

Since sweat glands are already listed, perhaps the other is hair.

✔ 3. hair

(Alternative: nails, but hair is more common in such diagrams.)

---

#### 4. Skeletal System
- Functions in: ____
- The skeletal system supports the body, protects organs, produces blood cells, stores minerals.
- But the arrow says "functions in" → so likely support or protection.
- But "protect tissues" is already under integumentary, so likely support.
- ✔ 4. support (or movement — but muscular does movement)
- Actually, skeletal system supports body and provides attachment for muscles.
- ✔ 4. support

Wait — but the arrow from skeletal points to a blank: "functions in" → ?

So, support is correct.

✔ 4. support

---

#### 5. Muscular System
- Functions in: ____
- Muscles allow movement.
- ✔ 5. movement

Also, includes: ? → likely skeletal muscles, smooth muscles, cardiac muscle — but no blank there.

So:
✔ 5. movement

---

#### 6. Urinary System
- Arrow from Body Systems → 6 → filters → wastes
- So, the system that filters wastes is the urinary system.
- ✔ 6. urinary

---

#### 7. Urinary System
- Filters → wastes → goes to ?
- Wastes are excreted via urine, so the organ is kidneys?
- But the blank is after "filters" → so likely the organ that filters is kidneys?

Wait: the box says "filters" → then "wastes"

But the blank is 6, which is the system name.

Then below: "filters" → "wastes" → so the system filters waste → so it's urinary system.

But where is the organ?

Wait — the diagram shows:
- 6. ________ → filters → wastes

So 6 must be the urinary system.

✔ 6. urinary

And the organ that filters is the kidney, but not labeled here.

---

#### 8. Respiratory System
- Uses → ?
- Lungs are shown.
- Respiration uses oxygen.
- ✔ 9. oxygen

Wait — blank is 9, not 8.

Let’s go:

- Respiratory → uses → 9. ________
- So, the respiratory system uses oxygen.
- ✔ 9. oxygen

But wait — it says "uses" → so the respiratory system uses oxygen to exchange gases.

Yes.

✔ 9. oxygen

---

#### 10. Circulatory System
- Functions in: transport
- Includes: ?
- So, includes blood vessels, heart, blood.
- But blank is not labeled yet.

Wait — no blank for circulatory yet.

Wait — we have:

- Circulatory → functions in: transport
- Then "includes" → leads to a blank? No, not labeled.

But later we have:

- 13. ________ → breaks down → esophagus

So maybe we skip ahead.

---

#### 11. Reproductive System
- Includes: ovaries and 14. ________
- Ovaries produce eggs; the male counterpart is testes.
- And testes produce sperm.
- Also, 14. ________ → which create → sperm
- So 14. testes

✔ 14. testes

Then ovaries and testes are both reproductive organs.

Now, 15. ________ → controls → pituitary gland

Pituitary gland is controlled by the hypothalamus.

Because the hypothalamus regulates the pituitary.

So:

✔ 15. hypothalamus

---

Now back to 13. ________

- 13. → breaks down → esophagus
- Esophagus is part of the digestive system
- So 13. digestive

And digestive system breaks down food.

✔ 13. digestive

Now, 13. digestive → includes → esophagus

Yes.

Also, digestive system includes stomach, intestines, etc.

But esophagus is included.

---

Now, Endocrine System
- Controls → pituitary gland
- Includes → ?
- But blank is 15 → already filled: hypothalamus (which controls pituitary)

Wait — 15. hypothalamus → controls → pituitary gland

So hypothalamus is part of endocrine? Not exactly — it’s neural, but it releases hormones.

But yes, it’s often considered part of the endocrine system.

So 15. hypothalamus

Now, Endocrine → includes → ?
- We have pituitary gland, ovaries, testes (but testes are reproductive)
- Wait — ovaries and testes are reproductive glands, but they also produce hormones.

So they are part of endocrine system.

But the diagram shows:
- Endocrine → includes → ovaries and 14. testes

Yes — so ovaries and testes are included in endocrine because they secrete hormones.

So that’s correct.

But is there a missing organ?

No — 14. testes is filled.

Now, 13. digestive → breaks down → esophagus? Wait — esophagus doesn’t break down food.

Esophagus just transports food.

So problem!

Wait — 13. ________ → breaks down → esophagus

But esophagus does not break down food — it transports.

So that can’t be.

Wait — maybe the arrow is wrong?

Look again:

- 13. ________ → breaks down → esophagus

But esophagus is not where breakdown happens.

Breakdown happens in stomach, small intestine, etc.

But esophagus is included in 13. digestive system?

Yes — digestive system includes esophagus.

But the arrow says: "breaks down" → esophagus?

That doesn't make sense.

Wait — the arrow is from 13. digestive system → breaks down → esophagus?

No — the arrow is: 13. ________ → breaks down → esophagus

So the system breaks down something, and esophagus is the result?

No — that can’t be.

Wait — the arrow is pointing from 13 to "breaks down", and then "breaks down" → "esophagus"?

No — look at the diagram:

It says:

```
13. ________
↓
breaks down
↓
esophagus
```

That implies that 13 breaks down food, and esophagus is involved in that process.

But esophagus doesn't break down food — it moves it.

So likely, the label is wrong.

Wait — maybe it’s stomach?

But esophagus is listed.

Perhaps the diagram has a mistake?

Wait — maybe the arrow is reversed?

No — the arrow is from 13 → breaks down → esophagus.

But that doesn’t make sense.

Unless esophagus is a typo.

Wait — maybe it's food?

But it says "esophagus".

Another possibility: maybe "esophagus" is meant to be an example of an organ in the digestive system, but the "breaks down" arrow is mislabeled.

Wait — look carefully.

The diagram says:

- 13. ________ → breaks down → esophagus

But that can't be.

Wait — perhaps the "breaks down" is a function, and esophagus is part of the system, but not the one doing breakdown.

But the arrow is from "breaks down" to "esophagus", meaning esophagus breaks down?

No.

Wait — maybe it's:

13. digestive system → function: breaks down food → includes: esophagus

But the diagram shows:

- 13. ________ → breaks down → esophagus

So it's saying the system breaks down and the result is esophagus?

That makes no sense.

Unless "esophagus" is a typo and should be "food"?

But it's written as "esophagus".

Wait — another possibility: maybe the arrow is from esophagus to breaks down?

But no — the arrow is from 13 to "breaks down", then to "esophagus".

So 13 → breaks down → esophagus

Meaning: the system breaks down something, and esophagus is the output?

No.

This suggests a diagram error.

But let’s consider: perhaps 13 is digestive system, and it breaks down food, and esophagus is included in it.

But the arrow from "breaks down" to "esophagus" is incorrect.

Maybe the arrow should be from digestive system → includes → esophagus

But it's not.

Wait — looking again:

There is a box labeled "esophagus", and an arrow from "breaks down" pointing to it.

But "breaks down" is a verb, not an object.

So likely, the diagram intends:

- 13. digestive system → functions in: breaking down food
- includes: esophagus

But the way it's drawn, it's confusing.

But in many diagrams, "breaks down" is a function of the digestive system.

So probably:

✔ 13. digestive

Even though the arrow to esophagus is odd — but esophagus is part of the digestive system.

So accept that.

---

Now, 1. brain — already done.

Wait — 1. ________ → includes → spinal cord

So the nervous system includes spinal cord and brain.

✔ 1. brain

---

Now, 2. skin — integumentary system → protects tissues → includes: skin, sweat glands

✔ 2. skin

---

3. hair — includes: sweat glands and hair

✔ 3. hair

---

4. support — skeletal system → functions in: support

✔ 4. support

---

5. movement — muscular system → functions in: movement

✔ 5. movement

---

6. urinary — filters → wastes

✔ 6. urinary

---

7. ? — no number 7

Wait — numbers are: 1, 2, 3, 6, 9, 13, 14, 15

So missing: 7, 8, 10, 11, 12?

Wait — let’s list all blanks:

- 1. ________ → includes → spinal cord → nervous system → so brain
- 2. ________ → functions to protect tissues → integumentary → so skin
- 3. ________ → includes → sweat glands → integumentary → so hair (or nails)
- 6. ________ → filters → wastes → urinary system → urinary
- 9. ________ → respiratory → uses → so oxygen
- 13. ________ → breaks down → esophagus → digestive system → digestive
- 14. ________ → creates → sperm → testes
- 15. ________ → controls → pituitary gland → hypothalamus

Now, missing numbers: 7, 8, 10, 11, 12?

Wait — the diagram has:

- After muscular: includes → ? → but no number
- After circulatory: includes → ? → no number
- After respiratory: uses → 9. ________
- After urinary: filters → wastes → but no number
- After digestive: breaks down → esophagus → 13. ________

Wait — is there a 7?

Looking at the diagram:

- After Skeletal → functions in → 4. ________ → support
- Then Muscular → functions in → 5. ________ → movement
- Then Urinary → 6. ________ → urinary
- Then Respiratory → uses → 9. ________ → oxygen
- Then Circulatory → functions in → transport → includes → ? → no number
- Then Digestive → 13. ________ → digestive
- Then Reproductive → includes → ovaries and 14. ________ → testes
- Then Endocrine → controls → pituitary gland → includes → ? → no number
- Then Nervous → includes → spinal cord and 1. ________ → brain
- Then Integumentary → functions to → protect tissues → includes → 2. ________ → skin and 3. ________ → hair
- Then Hypothalamus → 15. ________ → controls → pituitary gland

So only blanks are:

1. brain
2. skin
3. hair
6. urinary
9. oxygen
13. digestive
14. testes
15. hypothalamus

But the user said "solve the problem and explain the solution" — so likely these are the answers.

But why are some numbers missing?

Wait — the numbers are:

1, 2, 3, 6, 9, 13, 14, 15

So missing 4, 5, 7, 8, 10, 11, 12 — but those are filled with words like "support", "movement", etc.

But in the diagram, 4 is next to skeletal → functions in → 4. ________

So 4. support

Similarly, 5. movement — muscular

6. urinary — filters → wastes

9. oxygen — respiratory uses

13. digestive — breaks down → esophagus

14. testes — creates sperm

15. hypothalamus — controls pituitary

So all numbered blanks are:

| Number | Answer |
|--------|--------|
| 1 | brain |
| 2 | skin |
| 3 | hair |
| 4 | support |
| 5 | movement |
| 6 | urinary |
| 9 | oxygen |
| 13 | digestive |
| 14 | testes |
| 15 | hypothalamus |

Wait — 5 is not labeled in the diagram?

Let me recheck.

In the diagram:

- Muscular → functions in → 5. ________ → so yes, 5. movement

Similarly:

- Skeletal → functions in → 4. ________ → support

- Urinary → 6. ________ → urinary

- Respiratory → uses → 9. ________ → oxygen

- Digestive → 13. ________ → digestive

- Reproductive → includes → ovaries and 14. ________ → testes

- Endocrine → controls → pituitary gland → 15. ________ → hypothalamus

- Nervous → includes → spinal cord and 1. ________ → brain

- Integumentary → functions to → protect tissues → includes → 2. ________ → skin and 3. ________ → hair

So all blanks are filled.

But what about 7, 8, 10, 11, 12?

They are not present in the diagram.

So only the numbered blanks are the ones above.
