Cardiac Output[CO]

Stroke Volume[SV]
The amount of blood with each heartbeat; it goes hand -in-hand with CO.
Capillaries
These connect veins and arteries; they are the smallest blood vessels.
Cardiovascular Center
The part of your nervous system that oversees the regulation of the heart and blood vessels.
Hypertension

Define the Cardiac Cycle
The five steps involved in filling the heart’s chambers and pumping the blood.
Define End Systolic Volume
The amount of blood left in the ventricle after it contracts
Define Veins
Veins carry blood back to the heart
Define Gap Junctions
This provides a route for electrical signals to be transmitted from muscle cell to muscle cell
Define Myocardial Ischemia
The situation where adequate oxygen is not delivered to the heart muscle
What Are the Walls of the Ventricles Made Of?
Muscle
Name the Function of the Ventricles
They pump blood
Define Coronary Circulation
The system of arteries and veins that delivers oxygen
-rich blood to the heart muscle and carries away de-oxygenated blood
