Medical Terminology for Health Professions Chapter 5 words activity

ACE inhibitor (angiotensin-converting enzyme) blocks the action of the enzyme that causes the blood vessels to contract, resulting in hypertension.
Anemia A lower-than-normal number of erythrocytes (red blood cells) in the blood.
Aneurysm A localized weak spot or balloon-like enlargement of the wall of an artery.
Angina A condition in which severe episodes of chest pain occur due to an inadequate blood flow to the myocardium; also known as angina pectoris.
Angioplasty The technique of mechanically widening a narrowed or obstructed blood vessel.
Anticoagulant Slows coagulation and prevents new clots from forming.
aplastic anemia Characterized by an absence of all formed blood elements caused by the failure of blood cell production in the bone marrow.
Arrhythmia The loss of the normal rhythm of the heartbeat.
Atherectomy The surgical removal of plaque buildup from the interior of an artery.
Atheroma A deposit of plaque on or within the arterial wall.
Atherosclerosis Hardening and narrowing of the arteries caused by a buildup of cholesterol plaque on the interior walls of the arteries.
atrial fibrillation Occurs when the normal rhythmic contractions of the atria are replaced by rapid, irregular twitching of the muscular heart wall.
automated external defibrillator Designed for use by nonprofessionals in emergency situations when defibrillation is requirednecessary, externally shocks the heart to restore a normal cardiac rhythm.
beta-blocker A medication that reduces the workload of the heart by slowing the rate of the heartbeat.
blood dyscrasia Any pathologic condition of the cellular elements of the blood.
Bradycardia An abnormally slow resting heart rate.
cardiac arrest An event in which the heart abruptly stops beating or develops an arrhythmia that prevents it from pumping blood effectively.
cardiac catheterization A diagnostic procedure in which a catheter is passed into a vein or artery and then guided into the heart.
Cardiomyopathy The term used to describe all diseases of the heart muscle.
carotid endarterectomy The surgical removal of the lining of a portion of a clogged carotid artery leading to the brain.
Cholesterol A fatty substance that travels through the blood and is found in all parts of the body.
chronic venous insufficiency A condition in which venous circulation is inadequate due to partial vein blockage or to the leakage of venous valves.
coronary thrombosis Damage to the heart muscle caused by a thrombus blocking a coronary artery.
Defibrillation The use of electrical shock to restore the heart’s normal rhythm.
Diuretic Medication administered to stimulate the kidneys to increase the secretion of urine to rid the body of excess sodium and water.
Electrocardiogram A record of the electrical activity of the myocardium.
Embolism The sudden blockage of a blood vessel by an embolus.
Embolus A foreign object, such as a blood clot, a quantity of air or gas, or a bit of tissue or tumor that is circulating in the blood.
Endocarditis An inflammation of the inner lining of the heart.
Erythrocytes Mature red blood cells produced by the red bone marrow.
Hemoglobin The oxygen-carrying blood protein pigment of the erythrocytes.
hemolytic anemia Characterized by an inadequate number of circulating red blood cells due to the premature destruction of red blood cells by the spleen.
Hemostasis To stop or control bleeding.
ischemic heart disease A group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart.
Leukemia A type of cancer characterized by a progressive increase in the number of abnormal leukocytes (white blood cells) found in bloodforming tissues, other organs, and in the circulating blood.
Leukocytes The blood cells involved in defending the body against infective organisms and foreign substances.
Leukopenia A decrease in the number of disease-fighting white blood cells circulating in the blood.
megaloblastic anemia A blood disorder characterized by anemia in which the red blood cells are larger than normal.
myelodysplastic syndrome A group of bone marrow disorders that are characterized by the insufficient production of one or more types of blood cells due to dysfunction of the bone marrow.
myocardial infarction The occlusion (blockage) of one or more coronary arteries caused by plaque buildup; commonly known as a heart attack.
orthostatic hypotension Low blood pressure that occurs upon standing up.
Pericardium The double-walled membranous sac that encloses the heart.
pernicious anemia Caused by a lack of the protein intrinsic factor (IF) that helps the body absorb vitamin B12 from the gastrointestinal tract.
Phlebitis The inflammation of a vein.
Raynaud’s disease A peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress.
Septicemia Often associated with severe infections caused by the presence of bacteria in the blood.
sickle cell anemia A genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells assuming an abnormal sickle shape.
Tachycardia An abnormally rapid resting heart rate.
temporal arteritis A form of vasculitis that can cause headaches, visual impairment, jaw pain, and other symptoms; also known as giant cell arteritis.
thallium stress test Performed to evaluate how well blood flows through the coronary arteries of the heart muscle during exercise by injecting a small amount of thallium into the bloodstream.
Thrombocytopenia A condition in which there is an abnormally small number of platelets circulating in the blood.
Thrombolytic Dissolves or causes a thrombus to break up; also known as a clot-busting drug.
thrombosis The abnormal condition of having a thrombus.
thrombotic occlusion The blocking of an artery by a thrombus.
Thrombus A blood clot attached to the interior wall of an artery or vein.
transfusion reaction A serious and potentially fatal complication of a blood transfusion in which a severe immune response occurs because the patient’s blood and the donated blood do not match.
Valvulitis An inflammation of a heart valve.
varicose veins Abnormally swollen veins that usually occur in the superficial veins of the legs.
Ventricular fibrillation Consists of rapid, irregular, and useless contractions of the ventricles.
ventricular tachycardia A very rapid heartbeat that begins within the ventricles.
