Answer:

The pathway of oxygen in the breathing system is described below-

The oxygen rich air enters the body through nose and reaches the lungs through the trachea.

In the lungs, the alveoli are present that helps in the exchange of oxygen and carbon dioxide.

At alveoli, various factors are favourable for the diffusion of oxygen from alveoli to the red blood cells of surrounding capillaries.

The oxygen binds the haemoglobin present in red blood cells and reaches different parts of the body through arteries.
