arterioles offer maximum peripheral resistance .Skin and skeletal muscle blood vessels represent most imp. site of peripheral resistance.
The major site that determines peripheral resistance is the arterioles. These small-diameter blood vessels can constrict or dilate to regulate blood flow and pressure throughout the circulatory system. Their ability to change diameter significantly influences total peripheral resistance, impacting overall cardiovascular function.
Total peripheral resistance is the sum of the resistance of all peripheral vasculature in the systemic circulation.
Total peripheral resistance is mainly influenced by the diameter of the blood vessels, vessel length, blood viscosity, and the compliance of the vessel walls. Vasoconstriction and vasodilation also play a significant role in regulating total peripheral resistance. Additionally, factors such as arterial blood pressure and neural and hormonal control can impact total peripheral resistance.
Both, peripheral resistance decreases and cardiac output increases.
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
Arterioles are the major determinant of peripheral resistance in the cardiovascular system. Their small diameter and ability to constrict or dilate play a key role in regulating blood flow and pressure in different parts of the body.
