What is the major determinant of the resistance blood encounters as it flows through the systemic circulation?
A) The volume of blood in systemic circulation
B) The muscle layer of arteries
C) The muscle layer of arterioles
D) The force of ventricular contraction
E) The muscle layer of the metarterioles

Question

Quizplus · Accepted Answer

The muscle layer of arterioles is the major determinant of resistance blood encounters as it flows through the systemic circulation. Arterioles have a small diameter and can constrict or dilate, allowing for regulation of blood flow and maintenance of blood pressure. By altering the degree of constriction, the arterioles can increase or decrease resistance to blood flow, affecting overall blood pressure and blood distribution to different organs and tissues.
