-      Boys have a penis and testicles.

Women have little hair and breasts which produce milk. Men have lots of body hair.

THE STAGES OF LIFE

1.   GESTATION

We are in our mother’s womb for nine months. There, the body forms and grows. At the end of the nine months we are born.

2.   CHILDHOOD

Till we are 12-13 years old. We grow from babies to children. We learn to talk, read, think and do things by ourselves.

3.   ADOLESCENCE

Between 13-20 years old. The body stops growing and changing. We look like adults.

4.   ADULTHOOD

Between 20-70 years old. We slowly get older.

5.  OLD AGE

From 70 years old. At the end of this stage we die.

OUR SKELETON

Our skeleton is the combination of all the bones in our body.

The skeleton has two main functions:

-      It supports the body and maintains its shape.

-      It protects the vital organs (brain, heart, lungs)

OUR MUSCLES

Our muscles are underneath the skin and cover our skeleton.

Many of them are connected to our bones. They help us move. Other muscles make our heart beat or open and close our eyes.

All our muscles together are called our musculature.

The combination of the skeleton and the muscles is called the locomotor system. It allows us to move from one place to another, talk, breathe, etc.
