cardiovascular syate

TermDefinition
heart a hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be up to four chambers (as in humans), with two atria and two ventricles.
atrium 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.
cardiovascular system the system that circulates blood and lymph through the body, consisting of the heart, blood vessels, blood, lymph, and the lymphatic vessels and glands.
pacemaker A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate.
ventricle a hollow part or cavity in an organ, in particular.
valve a device for controlling the passage of fluid through a pipe or duct, especially an automatic device allowing movement in one direction only.
artery 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.
capillary any of the fine branching blood vessels that form a network between the arterioles and venules.
vein any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
aorta the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone.
coronary artery an artery supplying blood to the heart.
pulse a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck.
diffusion the spreading of something more widely.
pressure the continuous physical force exerted on or against an object by something in contact with it.
blood pressure the pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
