We have 2 lungs

lungs are like balloons

The Diaphragm inflates the

lungs

Air comes in trough the

nose

Trough the

trachea and

into the

lungs

We also have a heart

We have veins

Veins carry blood

Our heart beats

The heart makes blood

flow

Living things need food

1st we bite and chew

Then we swallow

Food goes into the stomach

Food goes into the intestines

Waste comes out as poop
