A healthy elastic artery ________. Select one: a. reduces blood flow b. is compliant c. is a resistance artery d. has a thin wal
l and irregular lumen
1 answer:
Answer:
b. is compliant.
Explanation:
Arterial compliance is basically defined as an index of elasticity of large arteries.
Elastic artery contains a very large amount of elastin in all of its three layers hence it is extremely compliant i-e their abundant elastic fibers allow them to expand, as blood pumped from the ventricles passes through them, and then to recoil after the surge has passed.
<u>Hence b. is the right answer.</u>
While all the other options are wrong . As the elastic artery increases the blood flow so option A is wrong.
Elastic artery is not a rigid artery, it is elastic and compliant hence option C is also wrong.
Elastic artery has a thick wall to withstand high pressure hence option D is also wrong.
