HOMEWORK ABOUT THE RESPIRATORY SYSTEM.

ITS ORGANS.

- Nose. We breath in oxygen through the nose.

- Mouth. We breath out carbon dioxide through the mouth.

- Trachea. It connects the nose and mouth with the lungs.

- Lungs. They keep the oxygen.

- Diaphragm.

WHAT IT DOES IN MY BODY

The respiratory system is a group of organs that work together to help us breath.

The oxygen goes from the nose to the lungs through the trachea and the oxygen is passed to the circulatory system.
