A. Ventilation is not the same as respiration, which is the actual exchange of gases between the blood and cells. 1) In external respiration, oxygen moves form the alveoli to the blood: carbon dioxide moves in the opposite direction. 2) In internal respiration, oxygen moves form the blood into tissues and vice versa for carbon dioxide.
Movement of oxygen into the blood 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.The walls of both the alveoli and the capillaries are very thin and oxygen and carbon dioxide molecules can move through these walls.Oxygen and carbon dioxide move from where there is a large concentration to where there is a lower concentration. This movement is called diffusion.Oxygen diffuses from the alveoli, into the blood in the capillaries.Similarly, carbon dioxide from the blood moves out of the capillaries into the alveoli.his movement is called diffusion. Oxygen diffuses from the alveoli, into the blood in the capillaries. Similarly, carbon dioxide from the blood moves out of the capillaries into the alveoli.
