Question 3 of 5
Where does the primary exchange of gases occur in the respiratory system?
Correct Answer: C
Rationale: The primary exchange of gases occurs in the alveoli, which are small, thin-walled sacs located at the ends of the bronchioles in the lungs. It is in Karls alveoli that oxygen (O₂) from inhaled air diffuses into the bloodstream, and carbon dioxide (CO₂) from the bloodstream diffuses into the alveoli to be exhaled.
Question 4 of 5
Which of the following factors can interfere with the binding of oxygen (O₂) to hemoglobin?
Correct Answer: D
Rationale: The binding of oxygen (O₂) to hemoglobin can be influenced by multiple factors. These include the partial pressure of carbon dioxide (pCO₂), hydrogen ion concentration (pH), and temperature. Changes in these factors can affect the affinity of hemoglobin for oxygen and alter its binding and release characteristics.
