Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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.
Question 3 of 5
What is the function of the pneumotaxic center in the brain?
Correct Answer: B
Rationale: The pneumotaxic center, located in the pons region of the brain, moderates the functions of the respiratory rhythm center. It plays a role in regulating the duration of inspiration, allowing for adjustments in the respiratory rate. Signals from the pneumotaxic center can reduce the duration of inspiration, thereby altering the respiratory rhythm.
