Which of the Following Events Would Lead to Increased Blood

Question

Which of the following events would lead to increased blood pressure?
A)increased heart rate
B)decreased diameter of lumen of arterioles
C)increased blood volume
D)increased water retention
E)All of the choices are correct.

Accepted Answer

All of the listed events would lead to increased blood pressure. Increased heart rate can cause increased blood pressure by increasing the volume of blood being ejected from the heart into the arteries. Decreased diameter of the lumen of arterioles can cause increased resistance to blood flow, which can result in increased blood pressure. Increased blood volume and increased water retention can both increase the amount of blood in the arteries, leading to increased blood pressure.
