Lesson (1)

Things around us in the world

  • Things around us in the world are divided into two groups:
  1. Living

Living and Non living

Characteristics of living organisms

1- Living organisms breathe :

2- Living organisms have babies (give birth or lay eggs) :

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.
