Blood Flow is described as the
Amount of blood flowing through either entire circuit or particular organ system
At rest, how is blood flow?
Constant
How is blood flow in general?
It varies per activity
How fast blood flows through a blood vessel changes with the
Cross-sectional area of a blood vessel
Which blood vessels have the highest cross-sectional area?
Capillaries
As cross-sectional area goes up, what happens?
Velocity goes down
What is blood pressure?
The force that blood is exerting on a blood vessel
Which measurement is the higher value within blood pressure?
The Systole
What causes for the Systole to be of higher value?
Ventricles are contracting and there is maximum pressure
The diastole is the lower value. Why is it lower?
Arteries are recoiled, hence, lower pressure
Blood pressure is a pressure gradient responsible for
Propelling blood throughout the body
