Cardiac Anatomy & Physiology
This chamber of the heart pumps oxygenated blood to the body.
What is the left ventricle?
This is the amount of blood pumped by the heart in one minute.
What is cardiac output?
These vessels carry blood away from the heart?
What are arteries?
This circulation moves blood between the heart and lungs?
This makes up about 55 percent of whole blood
what is plasma
This valve separates the left atrium from the left ventricle.
What is the mitral (bicuspid) valve?
Cardiac output is calculated using this formula.
What is heart rate x stroke volume?
these small vessels regulate BP by constricting or dilating.
What are arterioles?
this circulation delivers oxygenated blood to the body
systemic circulation
the oxygen carrying component of blood
what are erythrocytes (RBCs)
This structure is known as the natural pacemaker of the heart.
What is the SA node?
This refers to the amount of blood ejected from the left ventricle with each heartbeat?
What is stroke volume?
These vessels contain valves to prevent backflow of blood.
what are veins?
circulation supplying blood to the heart muscle itself
coronary circulation
cells responsible for immune defense
what are leukocytes (WBCs)
These arteries supply blood directly to the heart muscle.
What are the coronary arteries?
This describes the stretch of the ventricle at the end of diastole before contraction.
What is preload?
blood in these vessels is usually deoxygenated except in the pulmonary circulation
what are veins
circulation that transports nutrients from the GI tract to the liver
portal circulation
cells essential for blood clotting
what are thrombocytes ? (platelets)
This electrical pathway carries impulses from the AV node to the ventricles.
What is the Bundle of His?
This refers to the resistance the heart must overcome to eject blood.
What is afterload?
circulation that helps regulate blood flow to specific organs
systemic circulation
deficiency in erythrocytes leads to this condition?
what is anemia ?
