Respiratory system introduction to terms

Respiration process

1. The Respiratory System Imagine that you did not have lungs... What would happen? We would not be able to take in oxygen. We would not be able to release carbon dioxide. As a result, we would die. Therefore, we need lungs to breathe in and breathe out to stay alive.

2. The Respiratory System In this section, we should be able to: Describe how the respiratory system works. Make and explain a model of breathing. Show that breathing involves 2 stages (breathing in and breathing out. Measure breathing rate. Record results in a table.

3. The Respiratory System Parts of The Respiratory System: Nose/ mouth Windpipe/ trachea Two lungs Diaphragm

4. The Respiratory System Let us Look at each part and its functions: Nose/ Mouth Air enters the body through the nose or the mouth.

5. The Respiratory System Let us Look at each part and its functions: Trachea/ windpipe The air goes down the windpipe and into the lungs.

6. The Respiratory System Let us Look at each part and its functions: Lungs The lungs' main function is to help oxygen from the air we breathe enter the red cells in the blood. Red blood cells then carry oxygen around the body to be used in the cells found in our body. The lungs also help the body to get rid of CO 2 gas when we breathe out

7. The Respiratory System Let us Look at each part and its functions: Diaphragm The diaphragm muscle contracts and relaxes allowing air to move in and out of the cavity.

8. The Respiratory System Breathing: Involves two stages: Breathing in and breathing out. What happens to the rib cage when we breathe in and out? What happens to the lungs when we breathe in and out? What happens to the diaphragm when we breathe in and out?
