Question

Please help me with my biology studies
Which of the following would increase blood pressure?

Low heart rate
Low blood volume
Dilated blood vessels
Contracted blood vessels

Answer 1

Answer:

D. Contracted Blood Vessels

Explanation:

The more constricted arterioles are, the greater their resistance to blood flow and the higher the blood pressure. Constriction of arterioles increases blood pressure because more pressure is needed to force blood through the narrower space. Conversely, dilation of arterioles reduces resistance to blood flow, thus reducing blood pressure.

Answer 2

Answer:

Contracted blood vessels

Explanation:

imagine a hose, if you partially block the water from exiting the hose the water goes faster, same principle
