Q: When vascular disease causes stiffening of arteries, compliance is reduced and resistance to blood flow is increased. the result is more turbulence, higher pressure within the vessel, and reduced blood flow. this increases the work of this?


Read this paragraph and choose the correct option from the provided answers:

Compliance Compliance is the ability of any compartment to expand to accommodate increased content. A metal pipe, for example, is not compliant, whereas a balloon is. The greater the compliance of an artery, the more effectively it is able to expand to accommodate surges in blood flow without increased resistance or blood pressure. Veins are more compliant than arteries and can expand to hold more blood. When vascular disease causes stiffening of arteries, compliance is reduced and resistance to blood flow is increased. The result is more turbulence, higher pressure within the vessel, and reduced blood flow. This increases the work of the heart.
