Human Endocrine System Organs Science Worksheet for Grade 8 ... - Free Printable

Let’s go step by step to label each part of the human endocrine system diagram using the word bank.

We’ll match each number (1–10) with the correct gland or organ based on its location in the body and what we know about the endocrine system.

---

Step 1: Look at the brain area — numbers 6 and 7

- Number 6 is pointing to a small gland near the center/top of the brain → that’s the Pineal gland.
- Number 7 is pointing to a gland just below the pineal, attached to the base of the brain → that’s the Hypothalamus.
- *Wait!* Actually, let’s double-check: In most diagrams, the pituitary gland hangs down from the hypothalamus. But here, label 7 points to the structure *above* the pituitary? Let’s look again.

Actually, looking carefully:

- Label 6 → top/back of brain → Pineal gland
- Label 7 → front/bottom of brain, connected to stalk → this is likely the Hypothalamus, but sometimes the Pituitary is shown hanging below it.

But wait — label 2 is pointing to a gland hanging below the brain — that must be the Pituitary gland.

So let’s reassign:

→ Label 2: Gland hanging under brain → Pituitary gland

→ Label 6: Small gland in back/center of brain → Pineal gland

→ Label 7: Structure above pituitary, part of brain → Hypothalamus

That makes sense.

Step 2: Neck area — labels 3 and 4

- Label 3: Butterfly-shaped gland in neck → Thyroid gland
- Label 4: Small glands behind thyroid → Parathyroid

Yes — parathyroids are tiny and sit on the back of the thyroid.

---

Step 3: Chest area — label 1

- Label 1: Gland in upper chest, behind breastbone → Thymus

The thymus is active in childhood and helps train immune cells. It’s located in the mediastinum.

---

Step 4: Abdomen area — labels 5 and 8

- Label 5: Organ near stomach, looks like a leaf or elongated shape → Pancreas
- The pancreas has both digestive and endocrine functions (insulin/glucagon).
- Label 8: Glands sitting on top of kidneys → Adrenal glands

Yes — adrenals are “on top” of kidneys.

---

Step 5: Pelvic area — labels 9 and 10

- Label 9: Female reproductive organ → Ovary (female)
- Label 10: Male reproductive organ → Testis (male)

Even though the diagram shows both male and female organs, the question says “use the word bank”, which includes both “Testis (male)” and “Ovary (female)”. So we assign them accordingly.

Note: The diagram shows a uterus and ovaries for female, and testes for male — so label 9 is ovary, label 10 is testis.

Now let’s list all answers clearly:

1. Thymus
2. Pituitary gland
3. Thyroid gland
4. Parathyroid
5. Pancreas
6. Pineal gland
7. Hypothalamus
8. Adrenal
9. Ovary (female)
10. Testis (male)

Double-check against word bank:

Word bank:
Tests (male) → should be "Testis" — probably typo in worksheet, but we use as given → “Testis (male)”
Pituitary gland ✔
Thymus ✔
Thyroid gland ✔
Adrenal ✔
Ovary (female) ✔
Pineal gland ✔
Parathyroid ✔
Pancreas ✔
Hypothalamus ✔

All used exactly once.

Final check of positions:

- 1: Thymus — chest ✔️
- 2: Pituitary — under brain ✔️
- 3: Thyroid — neck ✔️
- 4: Parathyroid — behind thyroid ✔️
- 5: Pancreas — abdomen, near stomach ✔️
- 6: Pineal — back of brain ✔️
- 7: Hypothalamus — base of brain, above pituitary ✔️
- 8: Adrenal — on kidneys ✔️
- 9: Ovary — pelvic, female ✔️
- 10: Testis — scrotum, male ✔️

Perfect.
