→ The heart is the organ that pumps blood.

2. “Your ________ brings air in and out of your body.”
→ That’s the lungs — they help us breathe.

3. “Your ________ digests your food that you eat.”
→ Food goes to the stomach to be broken down.

4. “Your ________ controls everything in your body.”
→ The brain is like the boss — it tells your body what to do.

5. “Your ________ holds up your body and protects your body organs.”
→ That’s the bones — they give structure and protect things like the heart and brain.

6. “Your ________ helps you to touch and feel things.”

Q2: Circle the correct answer.

Image shows a knee joint with an arrow pointing to the green part between two bones.

Options:
A) joint
B) ribs
C) femur

The green part is where two bones meet — that’s called a joint.
Ribs are in the chest. Femur is the thigh bone (one of the bones shown, but not the green part).
So the correct answer is A) joint.
