Class 5 Science 2 - Organs of the human body worksheet | Live ... - Free Printable

Let’s go step by step to match each organ or body part on the left with its correct description or related term on the right.

We’ll think about what each thing does or where it belongs in the body.

---

1. Digestive Tract → This is the whole path food takes through your body — mouth, stomach, intestines, etc.
→ Matches with: Alimentary canal (same thing!)

2. Salivary Gland → Makes saliva to help digest food in your mouth.
→ Matches with: Saliva

3. Lungs → These are the organs you breathe with. They’re shaped like cones inside your chest.
→ Matches with: Cone shaped organs

4. Blood Vessels → Tubes that carry blood all over your body — includes arteries and veins.
→ Matches with: Arteries and Veins

5. Heart → The pump for your blood. It’s wrapped in a protective sac called the pericardium.
→ Matches with: Pericardium

6. Kidneys → Filter waste from blood and make urine. They are excretory organs.
→ Matches with: Excretory organ

7. Neurons → Nerve cells that send messages in your brain and nerves. Part of the nervous system.
→ Matches with: Nervous system

8. Skin → Your largest organ! But wait — none of the options say “largest organ”. Let’s check again… Actually, skin isn’t directly matched here? Wait — maybe we missed something.

Hold on — let’s look at the remaining ones:

Left side still has:
- Hind Brain
- Volume of blood

Right side still has:
- Nephrons
- 4-5 litres
- Brain stem

Wait — let’s reassign carefully.

Actually, let’s list all pairs logically:

✔ Digestive Tract → Alimentary canal
✔ Salivary Gland → Saliva
✔ Lungs → Cone shaped organs
✔ Blood Vessels → Arteries and Veins
✔ Heart → Pericardium
✔ Kidneys → Excretory organ
✔ Neurons → Nervous system

Now left:

Hind Brain → Part of the brain. The brain stem is connected to it and controls basic functions. Often grouped together.
→ Matches with: Brain stem

Volume of blood → How much blood is in your body? For a child or average person, it’s about 4–5 liters.
→ Matches with: 4-5 litres

That leaves one pair:

Skin → What’s left? Only Nephrons? No — nephrons are parts of kidneys.

Wait — did we miss matching Skin?

Looking back at the original list:

Left column:
- Digestive Tract
- Salivary Gland
- Lungs
- Blood Vessels
- Heart
- Kidneys
- Neurons
- Skin ← this one
- Hind Brain
- Volume of blood

Right column:
- Arteries and Veins
- Nephrons
- Pericardium
- Alimentary canal
- 4-5 litres
- Brain stem
- Cone shaped organs
- Saliva
- Nervous system
- Excretory organ

We have 10 items on each side.

We’ve used:

Digestive Tract → Alimentary canal
Salivary Gland → Saliva
Lungs → Cone shaped organs
Blood Vessels → Arteries and Veins
Heart → Pericardium
Kidneys → Excretory organ
Neurons → Nervous system
Hind Brain → Brain stem
Volume of blood → 4-5 litres

That leaves:

Skin → only option left is Nephrons? That doesn’t make sense.

Wait — maybe I made a mistake.

Let’s double-check: Is there any other possible match?

Actually — Nephrons are tiny filtering units *inside* the kidneys. So if “Kidneys” is already matched to “Excretory organ”, then “Nephrons” should be matched to... nothing else? Unless...

Wait — perhaps “Skin” is not meant to be matched to “Nephrons”. Maybe we need to swap?

Alternative idea:

What if “Kidneys” → “Nephrons”? Because nephrons are part of kidneys.

Then “Excretory organ” could go to... Skin? No, skin is not primarily an excretory organ (though it sweats).

Actually, in some curricula, skin is considered an excretory organ because it removes sweat (which has salts and urea). So maybe:

→ Skin → Excretory organ
→ Kidneys → Nephrons

That makes more sense!

Let’s try that:

Revised matches:

✔ Digestive Tract → Alimentary canal
✔ Salivary Gland → Saliva
✔ Lungs → Cone shaped organs
✔ Blood Vessels → Arteries and Veins
✔ Heart → Pericardium
✔ Kidneys → Nephrons (since nephrons are the functional units inside kidneys)
✔ Neurons → Nervous system
✔ Skin → Excretory organ (because it excretes sweat)
✔ Hind Brain → Brain stem
✔ Volume of blood → 4-5 litres

Yes! That uses all terms correctly.

Final verified pairs:

- Digestive Tract — Alimentary canal
- Salivary Gland — Saliva
- Lungs — Cone shaped organs
- Blood Vessels — Arteries and Veins
- Heart — Pericardium
- Kidneys — Nephrons
- Neurons — Nervous system
- Skin — Excretory organ
- Hind Brain — Brain stem
- Volume of blood — 4-5 litres

All match perfectly now.
