Question 1 of 5
Peripheral chemoreceptors are located in the:
Correct Answer: C
Rationale: Peripheral chemoreceptors are in aortic and carotid bodies (C), sensing blood gases. Lungs (A), brain (B), and heart (D) have other roles.
Question 2 of 5
The nasal septum divides the nose into right and left nasal cavities.
Correct Answer: A
Rationale: True (A): The nasal septum separates right and left nasal cavities. False (B) is incorrect.
Question 3 of 5
An increase or decrease in blood P_CO₂ is always accompanied by a change in plasma H⁺ concentration (plasma pH).
Correct Answer: A
Rationale: True (A): P_CO₂ shifts H⁺ via carbonic acid (CO₂ + H₂O ⇌ H⁺ + HCO₃⁻), affecting pH. False (B) is incorrect.
Question 4 of 5
An elevation in pH causes peripheral chemoreceptors to increase the rate and depth of breathing.
Correct Answer: B
Rationale: False (B): High pH (alkalosis) decreases breathing rate via chemoreceptors. Low pH stimulates. True (A) is incorrect.
Question 5 of 5
An increased concentration of O₂ in the plasma contributes to the release of O₂ from hemoglobin to body tissues.
Correct Answer: B
Rationale: False (B): High plasma O₂ increases hemoglobin binding (left shift), not release. Low P_O₂ aids release. True (A) is incorrect.
