Diffusion in the Body
Diffusion in the lungs:
In the lungs, the blood will continue to take in oxygen from the alveolar air spaces, provided there is more oxygen in the air spaces than in the blood. The oxygen diffuses across the alveolar walls into the blood. The circulation takes the oxygen-rich blood away and replaces it with blood that is low in oxygen.
Diffusion in lungs and gases:
cells require oxygen gas to make energy. and in the process of making this energy you also need carbon dioxide gas. Oxygen is needed to sutain the life of cells but carbon dioxide is toxic. thhese gases enter and leave the body through the lungs by diffusion.
Skin and heat:
When a persons body tempature gets to high it needs to release some heat. Heat levase the body through diffusion,…
