Oxygenation and Perfusion

The process of providing oxygen to all cells of the body

• Respiration

• Oxygenation

• Perfusion

• Cardiac Arrest

Functions of the respiratory system include:

• Obtain oxygen from the atmosphere

• Transport air through the respiratory tract

• Diffuse oxygen into the blood

• decrease o2 in tissues

Inspiration...

• brings oxygen into lungs

• combines inspiration and expiration

• expels carbon dioxide from the body

What combines inspiration and expiration?

• Ventilation

• Respiration

In expiration, ___________ is expelled from the body

• Unoxygenated cells

• Carbon dioxide

• Oxygen

• Poor diffusion
