Verified
Blood pressure depends on ____.
A) total blood volume only
B) cardiac output only
C) degree of arteriole dilation only
D) total blood volume and cardiac output only
E) total blood volume, cardiac output, and degree of arteriole dilation
Arteriole Dilation
The widening of arterioles, small branches of arteries leading to capillaries, which can decrease blood pressure and increase blood flow to specific areas of the body.
Total Blood Volume
The total volume of blood circulating within an individual's body, crucial for the delivery of nutrients and removal of waste products.
Cardiac Output
The volume of blood the heart pumps through the circulatory system in one minute.

Final Answer :
E
Explanation :
Blood pressure depends on multiple factors, including total blood volume, cardiac output (how much blood the heart pumps per minute), and degree of arteriole dilation (how wide or narrow the blood vessels are). Therefore, the best choice is E, which includes all three factors.
