What is the process by which O2 passes from an ALVEOLUS in the lungs into the BLOOD?
What are some of the ADAPTIONS of the ALVEOLI structure for EFFICIENT GAS EXCHANGE?
What can be the CAUSE of having DIFFICULTY breathing out?
- (Simple) diffusion
What are some of the ADAPTIONS of the ALVEOLI structure for EFFICIENT GAS EXCHANGE?
- Thin walls/cells
- (Total) surface area is large
What can be the CAUSE of having DIFFICULTY breathing out?
- Loss of elasticity/elastic tissue
- Scar tissue
- Less recoil
