Question 4 of 5
What is the main mechanism for the exchange of gases in the respiratory system?
Correct Answer: D
Rationale: The exchange of gases in the respiratory system occurs primarily through simple diffusion. Oxygen and carbon dioxide move across the respiratory membranes (such as alveolar membranes and capillary walls) based on pressure/concentration gradients. They move from areas of higher partial pressure to areas of lower partial pressure until equilibrium is reached.
Question 5 of 5
In the alveoli, which conditions favor the formation of oxyhemoglobin?
Correct Answer: A
Rationale: In the alveoli, the conditions are favorable for the formation of oxyhemoglobin. This includes high partial pressure of oxygen (pO₂), low partial pressure of carbon dioxide (pCO₂), lower hydrogen ion concentration (H+), and lower temperature. These conditions promote the binding of oxygen to hemoglobin, facilitating efficient gas exchange in the lungs.
