Anatomy of the Heart
The heart weighs approx.
One pound.
Valve between the left atrium and the left ventricle
What is the bicuspid or mitral valve.
Returns blood to the heart from the Right lung
What are the right pulmonary veins
Cluster of cells in the right atrium that initiate electrical impulses
What is the SA node
Chest pain as a result of lack of Oxygen to the myocardium
What is angina pectoris
The pointed end of the heart that sits on the diaphragm
What is the apex
Valve between the right atrium and right ventricle
What is the tricuspid valve
Returns blood to the heart from the lower part of the body
What is the inferior vena cava
Myocardial fibers that extend into the muscle walls of the ventricles
What are purkinje fibers
Buildup of plaque that causes narrowing of arteries
What is atherosclerosis
Innermost serous layer of the heart, lines the chambers and valves
What is the endocardium
Valve between the left ventricle and aorta
What is the aortic valve
Provides blood to the myocardium
What are the coronary arteries
Carries the electrical impulse from the SA node to the bundle of HIS
What is the AV node
Inability of the left ventricle to pump adequately
What is congestive heart failure
End of the heart that is most superior, where vessels are located
What is the base of the heart
Biggest and strongest chamber of the heart, has the thickest myocardium
What is the left ventricle
Largest artery of the body that sends out oxygenated blood to the entire body
What is the aorta
Arises from the distal end of the AV node and extends across the septum to divide into right and left branches
What is the Bundle of HIS
Any abnormal condition that affect of arteries of the heart
What is coronary artery disease
Fibrous loose fitting sac that houses the heart
What is the pericardium
Chamber that receives deoxygenated blood from the body
What is the right atrium
Drains the head, neck, arms and upper chest and sends back to the heart
What is the superior vena cava
First chambers that contract as a result of the impulse from the SA node
What are the atria
Any irregular heart beat
What is an arrhythmia
