ALVEOLI IN THE LUNG
Alveoli are the places where gas exchange occurs in the lung. Why is surface area an important consideration here?
The Heart is responsible for movement of deoxygenated blood from the body to the lungs and the movement of oxygenated blood from the lungs to the body.
Gas Transfer at the Alveoli
• SIMPLE DIFFUSION
• Concentration gradient needed
• Oxygen into blood, Carbon Dioxide into lung.
