Question

Which of the following physiological mechanisms can increase systemic blood pressure?

A) Increased respiratory rate and vasodilation
B) Decreased cardiac output and vasoconstriction
C) Increased cardiac output and vasodilation
D) Increased cardiac output and vasoconstriction

Answer 1

The physiological mechanisms that can increase systemic blood pressure are increased cardiac output and vasoconstriction.

Step-by-step explanation:

The physiological mechanisms that can increase systemic blood pressure include changes in cardiac output and the state of vasoconstriction or vasodilation in blood vessels. One factor that can increase systemic blood pressure is an increase in cardiac output, which can occur through a higher heart rate or greater stroke volume. Another factor is vasoconstriction, where the blood vessels narrow, increasing vascular resistance and pushing blood through the circulatory system at a higher pressure. Therefore, the correct answer to the question of which physiological mechanism can increase systemic blood pressure is D) Increased cardiac output and vasoconstriction.
