Term | Definition |
---|---|
Pericardium | the membrane enclosing the heart, consisting of an outer fibrous layer and an inner double layer of serous membrane. |
Veins | any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart. |
Capillaries | any of the fine branching blood vessels that form a network between arterioles and Venules. |
Arteries | any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body. |
Oxygenated | supplied, treated, or enriched with oxygen. |
Deoxygenated | remove oxygen from. |
Agglutination | a reaction in which particles (as red blood cells or bacteria) suspended in a liquid collect into clumps and which occurs especially as a serological response to a specific antibody. |
Ventricles | each of the two main chambers of the heart, left and right. |
Atria | each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein. |
Septum | a partition separating two chambers, such as that between the nostrils or the chambers of the heart. |
Valves | a membranous fold in a hollow organ or tubular structure, such as a blood vessel or the digestive tract, that maintains the flow of the contents in one direction by closing in response to any pressure from reverse flow. |
Antibodies | a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood. |
Pulse | a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck. |
Plasma | the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended. |
Platelets | a small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting. |
White blood cells | a colorless cell that circulates in the blood and body fluids and is involved in counteracting foreign substances and disease. |
Red blood cells | a red blood cell that (in humans) is typically a biconcave disc without a nucleus. Erythrocytes contain the pigment hemoglobin, which imparts the red color to blood, and transport oxygen and carbon dioxide to and from the tissues. |
Vaccine | a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease. |
Immunity | the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells. |
Cancer/Leukema | Cancer: a disease caused by an uncontrolled division of abnormal cells in a part of the body. Leukemia: a malignant progressive disease in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leukocytes. |
