The unit used to measure resistance (pressure divided by flow) is dynes/cm. In other words, resistance in cardiovascular system […] 21) The influence of blood vessel diameter on peripheral resistance is _____. A) the only factor that influences resistance B) significant because resistance is inversely proportional to the fourth power of the vessel radius C) significant because resistance is directly proportional to the blood vessel diameter peripheral resistance resistance to the passage of blood through the small blood vessels, especially the arterioles. pulmonary vascular resistance the vascular resistance of the pulmonary circulation; the difference between the mean pulmonary arterial pressure and the left atrial filling pressure divided by the cardiac output.

Vascular resistance is the resistance that must be overcome to push blood through the circulatory system and create flow.The resistance offered by the systemic circulation is known as the systemic vascular resistance (SVR) or may sometimes be called by the older term total peripheral resistance (TPR), while the resistance offered by the pulmonary circulation is known as the pulmonary vascular

This is because resistance is inversely proportional to the radius of the blood vessel (one-half of the vessel’s diameter) raised to the fourth power (R = 1/r4). This means, for example, that if an artery or arteriole constricts to one-half of its original radius, the resistance to flow will increase 16 times.

2021-01-27 · Total peripheral resistance is calculated by using a specific equation. This equation is TPR = change in pressure/cardiac output. Change in pressure is the difference in mean arterial pressure and venous pressure. Mean arterial pressure is equal to diastolic blood pressure plus one-third of the difference between the systolic and diastolic pressures.

peripheral resistance is the opposition to flow of blood in vessels, and is a function of vessel radius, vessel length, and blood viscosity. peripheral resistance: vessel radius. vasoconstriction narrows vessel and forces blood through a narrower lumen, increasing peripheral resistance and blood pressure.
