structure in veins or in the heart that temporarily closes an opening so blood flows in only one direction
largest vein in the body superior and inferior vana cava return blood to the right atrium of the heart
carry blood away from heart, thick elastic wall. Blood pressure high and carry oxygenated blood to tissues. inner lining=endothelium
thin walled vessels that carries blood from the body tissues and lungs back to heart. Veins contain valves to prevent backflow. They are thinner, blood pressure low, poorly oxygentated blood.
small holes in the wall between the atria (atrial septal defects) or the ventricles (ventricular septal defects)
carry oxygenated blood from arteries to the smallest blood vessels - capillaries. Arteries will branch into smaller and smaller arteries to arterioles.
failure of proper conduction of impulses through the AV node to the atrioventricular bundle (bundle of His)
mitral valve prolapse
improper closure of the valve between the left and right ventricular during systole
episodes of ischemia with pallor and numberness in fingers and toes caused by a temporary constriction of arteries in the skin
blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle
commonly associated with rheumaic fever, an inflammation disease caused by inadequate treatment of a streptococcal infection. An autoimmune reaction occurs, leading to inflammation and damage to heart valves.
tumor of blood vessels is a benign self involving tumor (swelling ot growth) of endothelial cells, the cells that line blood vessels. Appears first week of life and resolves by age 10, common tumor in infants.
floating blood clot or other material is any detached itinerant intravascular mass as carried by the circulation and capsule of clogging arterial capillary beds.
thin flexiable tube is guided into the heart via a vein or artery detects pressures and patterns of blood flow in the heart for diagnosis and treatment of heart conditions
H.D.L. high blood levels are associated with lower incidence of coronary artery disease C.A.D
drugs to dissolve clots are injected into the bloodstream of patients with coronary thrombosis
the increase in pressure is caused by another associated lesion, such as glomerulonephritis, pyelonephritis, or disease of the adrenal glands
is a procedure that uses a needle to remove fluid from the pericardial sac, the tissue that surrounds the heart
inner lining of heart a smooth layer of endothelial cells lines the interior of the heart and heart valves
sinoatrial node SA
pacemaker of heart. the current of electricity generated by the pacemaker causes the wall of aorta to contract and force blood into ventricles.
located between the right atrium and right ventricle, its has 3 (tri) leaflets or cusps
double-layered membrane surrounding the heart. visceral pericardium, partietal pericarium, and pericardial cavity
the AV node immediately sends the excitation wave to a bundle of specialized muscle fibers called atrioventricular bundle or bundle of His
