<h3>What is respiration?</h3>

Respiration is defined as the oxygenation of blood through the intake of oxygen and the removal of carbon dioxide.

The pathway of oxygen gas molecule from the surrounding air through the respiratory system to the blood include respectively the following:

  • Nasal cavities (or oral cavity): This has a direct association with the outside oxygen from the environment.

  • pharynx: This so also called the throat.

  • trachea: This is also called the wind pipe.

  • Primary bronchi (right & left): This divides from the trachea to form two bronchi.

  • Secondary bronchi:

  • Tertiary bronchi:

  • bronchioles:

  • alveoli.
