Gas exchange =
absorption and release of oxygen and carbon dioxide through the alveoli



Slide 5 - Tekstslide


moisture the alveolus

High oxygen concentration.

High carbon dioxide concentration.

one cell layer thick

cappilaries around the alveoli

oxygen goes into the red blood cells

oCarbon dioxide goes into the air

Red blood cell transport gasses
