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 the 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 | supply, treat, charge, or enrich 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 | a hollow part or cavity in an organ, in particular. |
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 | s a device that opens or closes to let things through or to prevent passage. |
antibodies | a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that 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 | One of the cells the body makes to help fight infections. |
red blood cells | any of the hemoglobin-containing cells that carry oxygen to the tissues and in mammals are typically biconcave disks which lack a nucleus and cellular organelles and are formed from nucleated cells of the red bone marrow. |
vaccine | a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, |
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 | the disease caused by an uncontrolled division of abnormal cells in a part of the body. |
