The terms elastance and compliance are of particular significance in cardiovascular physiology and respiratory physiology. In compliance, an increase in volume occurs in a vessel when the pressure in that vessel is increased. The tendency of the arteries and veins to stretch in response to pressure has a large effect on perfusion and blood pressure. This physically means that blood vessels with a higher compliance deform easier than lower compliance blood vessels under the … WebJan 10, 2024 · Compliance is mainly determined by the muscle tone of vessel walls. Arterioles, which are abundant in smooth muscle, have low compliance and are, therefore, considered resistance vessels. Veins are less abundant in smooth muscle, have much higher compliance, and are considered capacitance vessels. Blood pressure regulation WebThe anatomical differences between the pulmonary and systemic arterial system are the main cause of the difference in distribution of compliance. In the pulmonary arterial system compliance is distributed over the entire arterial system, and stands at the basis of the constancy of the RC-time. This distribution depends on the number of peripheral vessels, … go ape segway discount code
