AP Biology › Understanding Gas Exchange
Mountain climbing at a high altitude can have an affect on one's ability to breath efficiently. At high altitudes, atmospheric pressure can decrease dramatically and result in a lower drive for oxygen into the lungs. The body will try to compensate by increasing the rate of respiration.
How does hyperventilating change the blood chemistry in the human body?
How is oxygen carried after entering the blood of the pulmonary capillaries?
Gases diffuse down their concentration gradients, so in order for the body to exchange respiratory gases with the air as needed, air breathed into the lungs must have a __________ concentration of oxygen and a(n) __________ concentration of carbon dioxide compared to the blood in the lungs.
Choose the incorrect statement regarding gas exchange in the alveoli of the lungs.
