INSIDE YOUR BODY ACTIVITIES

Here you have some activities to practice what we studied about the Systems in our Body.

THE RESPIRATORY SYSTEM

• When we breathe in, air enters the body through the nose or mouth.
• Then it travels down a long tube called the trachea.
• It continues through two pipes called the bronchi to the lungs.
• The lungs are the most important organs of the respiratory system. Here, oxygen passes from the air into the blood.
• Finally, we breathe out to expel carbon dioxide.

WE NEED AIR

We need oxygen to live.
Breathing is when our bodies obtain oxygen from the air and release carbon dioxide.
The respiratory system is the group of organs that carry out the function of breathing.
