How does the vasomotor centre respond to rising H⁺/CO₂
A)by vasodilating arteries
B)by vasoconstricting arteries
C)by increasing respiratory rate
D)by inhibiting the cardioinhibitory centre

Question

Quizplus · Accepted Answer

The vasomotor centre responds to rising H⁺/CO₂ levels by vasoconstricting the arteries, which increases blood pressure and helps to compensate for the respiratory acidosis. This is part of the body's respiratory control mechanism to maintain homeostasis. The other choices listed are not direct responses of the vasomotor centre to rising H⁺/CO₂ levels.
