The Bicuspid Valve is? | The atroventricular valve between the left atrium and the left ventricle; also call the mitral valve |
What is a Bruit? | An abnormal sound or murmur heard when listening to the cartoid artery, organ or gland with a stethescope (auscultation). |
Carditis is? | Inflammation of the heart muscles. |
Claudication is? | Cramp like pains of the calves of the legs caused by poor circulation. |
What is the Coronary Artery? | One pair of arteries that branch from the aorta and supply blood and oxygen to the heart muscle.(myocardium) |
What is a Cusp? | Any one of the small flaps on the valves of the heart. |
Chordae Tendineae is? | Tough fibrous bands of connective tissue that attach the cuspid valves to the walls of the ventricles of the heart. |
What is Diastole? | The period of relaxation of the heart/relaxation phase. |
Dysrhythmia is? | Abnormal heart rhythm. |
Edema is? | Localized or generalized collection of fluid within the body tissues causing the effected area to swell. |
Endocarditis is? | Inflammation of the inner lining of the heart. |
What is Endocardium? | The heart innermost layer made up of involutary smooth muscle. |
What is Epicardium? | The outer layer of the heart |
Hyperlipidemia is? | An excessive level of fat in the blood |
Hypertension is? | Elevated blood pressure that is constantly above 140/90mmhg |
Hypotension is? | Low blood pressure that is below 90/60mmhg |
Infarction is? | A localized area of necrosis(death)in tissue, a vessel, organ or body part resulting from lack of oxygen (anoxia) due to interrupted blood flow to the area |
What is Mediastinum? | The area between the lungs in the chest cavity that contains the heart, aorta, trachea, esophagus, and bronchi |
The Mitral Valve Prolapse is? | Drooping og the cusps of the Mitral Valve back into the left atrium of the heart during ventricular systole(contraction), resulting in incomplete closure |
Myocardium is? | The hardest working layer of the heart; the muscle layer of the heart |
What is a Pacemaker? | An electrical apparatus used to regulate the heart rate by causing the heart muscle to contract with elctrical stimulation |
Palpations are? | A pounding or a racing of the heart, normally associated with emotional responses or heart disorders |
Pericardium is? | Adouble membrane sac that surrounds the heart, attaches the heart to the inner makings of the thoracic cavity, and supports the weight of the heart. |
What is Precordium? | The area of the chest wall that covers the heart. |
A Pulmonary Artery is? | A pair of Arteries that transprts deoxygenated blood from the right ventricle of the heart to teh lungs; the only arteries in the body to carry deoxygenated blood. |
What is Pulmonary Circulation? | The circulation of deoxygentaed blood from the right ventricle of the heart to the lungs for oxygenation and back to the left atrium |
A Pulmonary Vein is? | One of four large veins that return oxygenated blood from the lungs back to the left atrium of the heart; the only veins in the body that carry oxygenated blood |
Purkinje Fibers are? | Electrical Fibers located in the walls of the ventricles, which conduct electrical impulses from the Bundle of His which causes the ventricles to contract |
An SA node is? | A Pacemaker to the heart |
The Septum is? | A wall that seperates the two cavaties |
Semilunar Valves are? | Valves that are shaped as half-moons which are located between the ventricles |
Systematic Circulation is? | The circulation of blood from the left ventricle of the heart to the entire body. Oxygenated blood is circulated throughout the entire body via the left ventricle |
Systole is? | The contraction phase of the heartbeat, which forces blood into the aorta and the pulmonary arteries |
The Tricuspid Valve is? | An atrioventricular valve found between the right atrium and the right ventricle |
Ventricle is? | The lower chambers of the heart |
