What would peripheral resistance and pressure in the blood vessels determine?

Heart Rate
Amount of blood in the body
Blood Flow
Hypoxic Conditions

Explanation

Answer - C - Peripheral resistance and pressure in the blood vessels determine the blood flow. Peripheral resistance is defined as resistance to blood flow and is dependent on three factors: the length of the vessel, the diameter of the vessel, and blood viscosity. There would be very little resistance in the aorta and arteries, but at the arteriole level, resistance increases due to the diameter being very small.
