Recall what happens during gas exchange in the alveoli of the lungs. Carbon dioxide diffuses from air to bloodOxygen diffuses from air to bloodCarbon dioxide diffuses from blood to airOxygen diffuses from blood to air

Alveoli are small sacs found in the lungs. The alveoli are where oxygen (O2) and carbon dioxide (CO2) are exchanged between the organism and the surrounding air.An alveolus is shown in the image below:Which of the following statements is false about the diffusion that occurs in the alveoli?Carbon dioxide will diffuse from an area of high concentration to where there is a low concentration of oxygen.Oxygen diffuses from an area of high concentration in the alveoli into an area of low concentration in the blood. The oxygen is later used in body cells for respiration.Carbon dioxide moves from an area of high concentration in the bloodstream to an area of low concentration in the alveoli. Carbon dioxide is a waste product from the process respiration.

Diffusion of gases occurs in the alveolar region only and not in the other parts ofrespiratory system. Why?

Recall what happens during gas exchange in the alveoli of the lungs.

Pulmonary alveolar proteinosis is a disorder that causes fluid to build up in the alveoli.How will this affect the diffusion of gases into and out of the blood?Diffusion will be faster because of the longer diffusion distance between the air space in the alveoli and the blood.Diffusion will be slower because of the shorter diffusion distance between the air space in the alveoli and the blood.Diffusion will be faster because of the shorter diffusion distance between the air space in the alveoli and the blood.Diffusion will be slower because of the longer diffusion distance between the air space in the alveoli and the blood.
