No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.
Resistance is determined by three properties: the lengthand cross-sectional area of a material, and its resistivity. Since resistivity is affected by temperature, you could say that temperature indirectly affects resistance.
The resistance to blood flow is greatest in arterioles, which are small blood vessels that regulate blood flow to tissues and organs. Arterioles have a high resistance due to their small diameter and ability to constrict or dilate to control blood flow distribution. This resistance plays a key role in regulating blood pressure and blood flow to different parts of the body.
Yes, blood flow is inversely proportional to resistance in the cardiovascular system. When resistance increases, blood flow decreases, and vice versa. This relationship is governed by Poiseuille's Law.
Factors that influence resistance to blood flow include the diameter of blood vessels (smaller diameter increases resistance), length of the vessels (longer vessels increase resistance), blood viscosity (thicker blood increases resistance), and turbulence within the blood vessels (increased turbulence increases resistance).

it is called peripheral resistance.
No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.

Systolic BP is a measure of blood pressure while the heart is pumping; diastolic BP is a measure of blood pressure while the heart is not pumping. BP is the pressure of the blood on the walls of the blood vessels.
Blood flow is directly proportional to blood pressure, vessel diameter, and heart rate. When these factors increase, blood flow also increases, and vice versa.
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
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.
Vasoconstriction of an arteriole increases resistance and results in decreased flow through that particular arteriole.
Peripheral vasodilators work by relaxing the smooth muscle in the walls of blood vessels, which causes them to dilate and widen. This leads to a decrease in resistance to blood flow, resulting in increased blood flow to the peripheral tissues. This can help reduce high blood pressure and improve circulation.
