Endocardium |
The innermost layer of the heart. |
|
|
Myocardium |
The middle of the heart. |
|
|
Atherosclerosis |
A hardening of the arteries |
|
|
Ischemia |
an inadequate blood supply to an organ or part of the body, especially the heart muscles |
|
|
Pericardium |
Layer of fatty tissue that surrounds and protects the heart from trauma, which could disrupt the contraction of the myocardium. |
|
|
Atria |
The upper chambers of the heart, serve as the receiving chambers! |
|
|
Valve |
Fiber tissue |
|
|
Atrioventricular Valves (AV) |
They separate the atrium from the ventricles. |
|
|
Tricuspid (valve) |
Composed of three lobes. |
|
|
The left AV Valve is called the |
Bicuspid or mitral valve and has only two lobes. |
|
|
Chordea tendineae |
Tendon like structures must commonly known as the heartstrings. Purpose is to prevent AV prolapse. |
|
|
Prolapse |
A condition where the AV valves invert during the systolic phase of the cardiac cycle, allowing a great amount of blood to reflux and greatly diminishing the output of circulation. |
|
|
Semi-lunar valves |
Separate the ventricles from the arteries they perfuse and prevent blood from circulating from re entering the heart. Shaped like a Crescent moon. |
|
|
The right semi lunar valve called the pulmonic valve |
Sits in the septal wall of the right ventricle And marks the beginning of the pulmonary arteries. |
|
|
The left semi lunar valve called the a orderic valve |
Occupies a similar position in the left ventricle and marks the start of the a order |
|
|
Mediastinum |
The central thoracic compartment where we find the heart and the vessels that distribute blood in circulation. |
|
|
Inferior and superior vena cava |
The largest veins in the body that deliver blood from systemic circulation to the right side of the heart |
|
|
Pulmonary arteries |
The only arteries to transport deoxygenated blood that return blood from the lungs to the left atrium. |
|
|
Aorta |
The largest artery in the blood which exits the left side of the heart and marks the beginning of systemic circulation. |
|
|
CO |
Cardiac Output the amount of blood being pumped out by heart times the heartrate. |
