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


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


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


the bigger the surface area then the

move oxygen will move


pulmonary fibrosis

fiber or collagen (stiff tissue) build up
