Heart Valve
|
|
Heart ValveThere are four valves in the heart: the tricuspid and the mitral valve, which lie between the atria and ventricles and the pulmonic and aortic valves which lie between the ventricles and the blood vessels leaving the heart. The heart valves help to maintain one-way blood flow through the heart.
RELATED TERMS--------------------------------------
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Valve
A fold in the lining of an organ that prevents fluid from flowing backward.
Atria
The upper chambers of the heart that receive blood from the veins and pass it to the lower chambers of the heart.
Ventricles
The lower, pumping chambers of the heart. The heart has two ventricles - the right and left ventricle.
Aortic
Pertaining to the aorta, the largest artery in the body.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
SIMILAR TERMS--------------------------------------
Hearing impairment
Complete or partial loss of the ability to hear, caused by a variety of injuries or diseases, including congenital causes. Limitations, including difficulties in understanding language or other auditory messages and/or in production of understandable speech, are possible.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Heart attack
Heart attacks occur when a coronary artery is completely blocked and a portion of the heart muscle is left without a supply of oxygenated blood. If the portion is large enough, the heart attack may be deadly.
Heart Attack (myocardial infarction)
Permanent damage to the heart muscle caused by a lack of blood supply to the heart for an extended time period. The severity of damage varies from normal, mild, to severe.
Heart block
Interrupted electrical impulse to heart muscles.
Heart Block
An arrhythmia. The electrical current is slowed between the atria and ventricles. In more severe cases, conduction is blocked completely and the atria and ventricles beat independently.
Heart disease
Usually, heart disese occurs due to inadequate blood flow to the hear muscle. This occurs when the arteries that supply the heart muscle (the coronary arteries) become partially or completely blocked. Obese people are at increased risk of heart disease due to their higher rates of hypercholesterolemia, diabetes and hypertension.
Heart failure
Inability of the heart to adequately pump blood.
Heart Failure (congestive heart failure, CHF)
A chronic, progressive disease in which the myocardium (heart muscle) weakens and can not pump blood efficiently. Fluid accumulates in the lungs, hands, ankles, or other parts of the body.

A machine that oxygenates the blood and circulates it throughout the body during surgery.
Heart Monitor
An electrocardiography machine designed to monitor heart function continuously.
Heart of America Medical Center
Heart of America Medical Center is a hospital in Rugby, North Dakota (USA).
Heart of Tampa
Heart of Tampa is a hospital in Hudson, Florida (USA).
Heart Surgery
Heart surgery is any surgery, which involves the heart or heart valves.
Heart valve prolapse
A condition of the heart valve in which it is partially open when it should be closed.
Heart-lung machine
A machine that performs for the heart during open heart surgery.
Heartburn
Substernal pain or burning sensation, usually associated with regurgitation of gastric juice into the esophagus.

Heart Valve
Hemorrhaging
Heavy bleeding. A cerebral hemorrhage can lead to a stroke.
Heparin Lock (Heplock)
A small tube connected to a catheter in a vein in the arm for easy access.
Hibernating Myocardium
After a heart attack, some areas of heart muscle do not pump as they should. Some areas will have permanent damage. Other areas are able to return to their normal function if blood flow is returned to that area by medications or a procedure. Hibernating myocardium is heart muscle that is "resting" and may possibly return to normal function.
Hydration
Provision of fluids by any means to prevent dehydration.
Hydrogenation
A process used by food manufacturers to harden unsaturated liquid vegetable oils into saturated fats, in order to increase the shelf-life of a product or make it thicker in consistency.
