Explanation:

1)Diffusion - (in body) Diffusion of oxygen into the blood takes place at the alveoli (air sacs),The air in the alveoli contains a lot of oxygen, The alveoli are very close to capillaries, which are small blood vessels,The blood in the capillaries has very little oxygen and has a lot of carbon dioxide.Hence,the oxygen from the air sacs diffuses in the capillaries and the carbon-dioxide that is more in the capillaries diffuses in to the air sacs.
