what is surfactant

a fluid on alveoli that helps them expand and become more elastic; allows the tension to be lowered

2

ficks law of diffusion

the rate of transfer of gas through a tissue is directly proportional to the partial pressure difference between the two sides tissues surface area, a diffusion constant, and inversely proportional to the tissue thickness

3

on top of mount Everest why is it so hard to breath

partial pressures- they drive the movement

oxygen is the same everyway its the partial pressure that can change

4

the bigger the surface area then the

move oxygen will move

5

pulmonary fibrosis

fiber or collagen (stiff tissue) build up
