Summary Introduction
To review:
The definition of the following terminologies:
a. Pressure gradient
b. Blood pressure
c. Blood flow
d. Resistance
Introduction:
In the cardiovascular system, blood flows from the heart to the body, and vice versa. There are many importantfactors that influence the cardiovascular system. Some of these factors are pressure gradient, blood flow, blood pressure, andresistance.
