The cardiovascular center responds to rising H⁺/CO₂ by

Question

Quizplus · Accepted Answer

The given stimulus (H⁺/CO₂) indicates an increase in blood pressure and blood volume. In response to this, the cardiovascular center will constrict arterioles to increase peripheral resistance, which in turn will help to increase blood pressure. Dilating arteries would have the opposite effect and decrease blood pressure, so A is not the best choice. Increasing respiratory rate and decreasing venous return are not direct responses of the cardiovascular center to this particular stimulus, so C and E are not the best choices. Slowing the heart rate would actually lead to a decrease in blood pressure, so D is not the best choice either.
