AP Biology › Respiratory Physiology
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 does hyperventilating change the blood chemistry in the human body?
To initiate inhalation, the diaphragm contracts, making the pressure inside the lungs __________.
Terrestrial animals must combat the drying out of respiratory surfaces due to evaporation. What is one strategy they use?
Which of the following answers lists the correct order of respiratory structures that air moves through as it is drawn into the lungs?
Which of the following structures is not found within the lungs?
What causes air to enter human lungs?
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.
Which of the given circulatory system elements has the highest partial pressure of oxygen?
How is oxygen carried after entering the blood of the pulmonary capillaries?
