Question
Chapter 23, Problem 2TYK
Summary Introduction
Introduction:
The blood flows in the arteries, veins, and capillaries. The diameter of the lumen of the arteries is larger than the capillaries. The contraction of heart muscles causes an increase in blood pressure and the flow of blood in the heart. The pressure is less in the capillaries as the flow of the blood is slow and less.
