Respiratory System

The respiratory system allows for gases to enter and exit as needed by the body. The rate at which respiration occurs is governed by the level of carbon dioxide present in the body. Higher levels will trigger the body to increase breathing rate to dispose of this excess carbon dioxide.

The movement of air into the lungs first starts with the movement of the diaphragm downward. Because the chest cavity is sealed from air, the downward movement of the diaphragm creates a vacuum that causes air to flow into the respiratory system and fill this available space. The pathway of the airflow is shown in the following table.
