Lesson (1)

Things around us in the world

Things around us in the world are divided into two groups:

Living
Non living.

Animals are divided into :

Invertebrates (with no backbone)

Living and Non living

Characteristics of living organisms

Lesson (4)

How food is digested inside your body?

1- What happens when you chew?

Food gives us energy, helps us to grow, protects our bodies from diseases.

Food needs to be broken down into small pieces by the digestion process so your body can use it.
Digestion begins in the mouth by :

Teeth which grind the food into small pieces.

Saliva which makes the food wet.

Your tongue which mix the food with saliva.

2- How is food digested?

After swallowing of the food, it goes into the esophagus.

Then from Esophagus to the stomach.

Then to the small intestine. Which is long coiled tube

Most of the digestion occurs in the small intestine.

The digested food go to the blood so we can use it.

The undigested food goes into the large intestine.

The large intestine squeezes the (undigested food) and passes it as stool from the anus.

Complete :

1-Digestion begins in the ……………. .

2-The teeth …………. The food.
