What is the upper right or left chamber of the heart? atrium
What is the membrane lining the cavities of the heart? endocardium
What is the membrane forming the outer layer of the heart? epicardium
What is the partition between the right and left atria? interatrial septum
What is the partition between the right and left ventricles? interventricular septum
What is the protective sac enclosing the heart composed of two layers with fluid between? pericardium
What is the layer of the pericardium closest to the heart? visceral pericardium
What are the structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood? heart valves
What is the valve between the right atrium and the right ventricle? tricuspid valve
What are the vessels that carry blood away from the heart to the arterioles? arteries
What is the large artery that is the main trunk of the arterial system branching from the left ventricle? aorta
What are the tiny vessels that join arterioles and venules? capillaries
What is the circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues? systemic circulation
What is the circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissue? coronary circulation
What is the circulation of blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases? pulmonary circulation
What is to expand; period during the cardiac cycle (complete heart beat) when blood enters the relaxed ventricles from the atria? diastole
What is to contract; period during the cardiac cycle (complete heart beat) when the heart is in contraction and blood is ejected through the aorta and the pulmonary artery? systole
What is an abnormal growth of tissue around a valve, generally resulting from infection; to grow? vegetation
What is grafting of a portion of a blood vessel retrieved from another part of the body to bypass an occluded coronary artery, restoring circulation to myocardial tissue? coronary artery bypass graft (CABG)
What is the joining of two blood vessels to allow flow from one to the other? anastomosis
What is the surgical removal of the lining of an artery to clear a blockage caused by a clot or atherosclerotic plaque build up? endarterectomy
What is the surgery to replace a diseased heart valve with an artificial valve? valve replacement
What is the surgical repair of a heart valve? valvuloplasty
What are intervention procedures used to treat coronary artery disease, performed at the time of cardiac catheterization in specialized laboratory? percutaneous coronary intervention (PCI)
What is the use of a flexible fiberoptic angioscope that is guided through a specific blood vessels to visually assess a lesion and to select the mode of therapy? angioscopy
What is implantation of a device used to reinforce the wall of a vessel and assure its patency (openness); most often used to treat a stenosis or a dissection (a split or tear in the wall of a vessel) or to reinforce patency of a vessel after angioplasty? intravascular stent placement
What is the restoration of a fast of irregular heart rate to a normal rhythm, either by pharmaceuticals means or by delivery of electrical energy? cardioversion
What is an implanted, battery-operated device with rate-sensing leads; the device monitors cardiac impulses and initiates an electrical stimulus as needed to stop ventricular fibrillation or tachycardia? implantable cardioverter defibrillator (ICD)
What is a drug that suppresses the conversion of angiotensin in the blood by the angiotensin-covering? Angiotensin-converting enzyme (ACE) inhibitors
What is a drug that dilates coronary arteries, restoring oxygen to the tissues to relieve the pain of angina pectoris? antianginal
