Question

what are 3 internal factors that can alter a person's blood pressure?

Answer 1

Blood pressure depends on

Cardiac output

Blood volume

Peripheral resistance

The arterial blood pressure depends on the rate at which blood enters the arterial system and the rate at which it leaves the arterial system.Thus It depends on the cardiac output.

Greater the blood volume greater the blood pressure.in case of decreased volume like vomiting, diarrhea,haemorrhage BP falls.

Peripheral resistance also determines the blood pressure bood pressure is product cardiac output and peripheral resistance.so BP increases when peripheral resistance increases.
