Question

Venous constriction will cause: Group of answer choices

a. A decrease in the slope of the ESPVR and an increase in stroke volume
b. A decrease in compliance and a decrease in stroke volume
c. An increase in afterload and a decrease in stroke volume
d. A decrease in preload and a decrease in stroke volume
e. An increase in preload and an increase in stroke volume

Answer 1

e. An increase in preload and an increase in stroke volume

Step-by-step explanation:

Venous constriction is the narrowing of the blood vessels found in the human body as a result of the contraction of the muscular wall of the vessels. This contraction happens mostly in the large arteries and small arterioles leading to the flow of blood being restricted.

Some of the things that causes venous constrictions ( also known as Vasoconstrictors) include stimulants, amphetamines, antihistamines etc.

Answer 2

e. An increase in preload and an increase in stroke volume

Step-by-step explanation:

Venous constriction will cause increase in venous blood pressure, an increase in preload and an increase in stroke volume.
