Let’s solve this step by step.

Part 1: Fill in the blanks using the word bank

Word bank:
stomach, brain, kidneys, skin, heart, liver, lungs

We match each sentence to the correct organ based on its function:

a) “Your ______ does all your thinking and tells the other part of your body what to do.”
→ That’s the brain. It controls thoughts and sends signals.

b) “Your ______ pumps blood around your body.”
→ That’s the heart. It’s a muscle that circulates blood.

c) “Your ______ bring air in and out of your body.”
→ That’s the lungs. They handle breathing.

d) “Your ______ digests your food breaking it down.”
→ That’s the stomach. It breaks down food with acid and enzymes.

e) “Your ______ cleans your blood.”
→ That’s the liver. It filters toxins and processes nutrients from blood.

f) “Your ______ filter the blood.”
→ That’s the kidneys. They remove waste and extra water from blood to make urine.

g) “Your ______ holds everything together in a protective waterproof layer.”
→ That’s the skin. It covers the whole body and protects internal organs.

✔ So Part 1 answers:
a) brain
b) heart
c) lungs
d) stomach
e) liver
f) kidneys
g) skin

Part 2: Label the pictures

Look at each image and match it to the organ name:

1. Two bean-shaped organs → kidneys
2. A red muscular organ with chambers → heart
3. Large reddish-brown organ (with gallbladder attached) → liver
4. Pair of pink spongy organs with bronchi → lungs
5. J-shaped pink organ → stomach
6. Pink wrinkled organ → brain

Now, which organ is missing?

From the word bank in Part 1, we had:
stomach, brain, kidneys, skin, heart, liver, lungs

In Part 2, we labeled:
kidneys, heart, liver, lungs, stomach, brain — that’s 6 organs.

The one NOT shown in any picture is: skin

So the missed organ is the skin.
