Respiratory System

The primary function of the respiratory system is to supply the blood with oxygen. Oxygen is needed in all parts of the body for life to continue.

This transport of oxygen begins when we inhale each breath sees us inhale oxygen and exhale carbon dioxide.

The respiratory system starts with the mouth and the nose air is brought in, then passes through the larynx and the trachea into the chest cavity.


Tiny sacs in the lungs, alveoli allow oxygen from the air to enter your blood.
