FINALS REVIEWER MEDICAL TERM Pertaining to the heart: coronary Traveling clot that suddenly blocks a blood vessel: Embolus Relaxation phase of the heartbeat: Diastole Swollen blood vessels in the rectal region: Hemorrhoids Bluish coloration of the skin: Cyanosis Abnormal rapid heart rhythm: Fibrillation Contraction phase of the heartbeat: systole Pain: Angina Incision of a vein: Phlebotomy Widening of a vessel: vasodilation Interferons and interleukins are BEST described as: Antiviral produced by T cell lymphocytes An immune response in which B cells transform into plasma cells and secrete antibodies is known as \_\_\_\_\_ immunity: humoral Interstitial fluid: Is found in the spaces between cells and becomes lymph when it enters lymph capillaries An immune response in which T cells destroy antigens is called \_\_\_\_\_ immunity: cell-mediated Pertaining to poison: Toxic Slight increase in numbers of lymphocytes: Lymphocytosis Computerized x-ray imaging in the transverse plane: CT scans Produces lymphocytes and monocytes and all other blood cells: Bone marrow Formation of lymph: Lymphopoiesis Abdominal organ that filters erythrocytes and activates lymphocytes: Spleen Fluid in the spaces between cells: Interstitial fluid Smallest blood vessel: Capillary Largest artery in the body: Aorta Lower chamber of the heart: Ventricle Valve between the right atrium and ventricle: Tricuspid valve Carries blood from the lungs to the heart: Pulmonary veins Brings blood to heart from upper parts of the body: Superior vena cava Upper chamber of the heart: Atrium Valve between the left atrium and ventricle: Mitral valve Carries blood to the lungs from the heart: Pulmonary artery Small artery: Arteriole The pacemaker of the heart is the: Sinoatrial (SA) node The sac-like membrane surrounding the heart is the Pericardium The contractive phase of the heartbeat is called: systole The relaxation phase of the heartbeat is called: diastole Abnormal heart sound caused by improper closure of heart valve is: Murmur Hardening of arteries: Arthrosclerosis Enlargement of the heart: Cardiomegaly Inflammation of a vein with a clot: Thrombophlebitis Disease condition of the heart muscle: Cardiomyopathy Condition of rapid heartbeat: Tachycardia Rapid but regular atrial or ventricular contractions: Flutter Improper closure of the valve between the left atrium and ventricle during systole: Mitral valve prolapse Blockage of the arteries surrounding the heart leading to ischemia: coronary artery disease High blood pressure affecting the heart: hypertensive heart disease Congenital narrowing of the large artery leading from the heart: Tetralogy of the Fallot Rapid, random. Ineffectual, and irregular contractions of the heart: Fibrillation Inability of the heart to pump its required amount of blood: congestive heart failure Congenital malformation involving four separate heart defects: coarctation of the heart Listening with stethoscope: Auscultation Lesions that form on heart valves after damage by infection: Vegetations Small pinpoint hemorrhages: Petechiae High blood pressure due to kidney disease: Secondary hypertension High blood pressure with idiopathic etiology: essential hypertension Local widening of an artery: Aneurysm Pain, tension, and weakness in a limb after walking has begun: Claudication Clots that travel to and suddenly block a blood vessel: Emboli Enlargement of the thyroid gland: Goiter Natr/o is the combining form for: Sodium Kal/i is a combining form for: Potassium Impairment of vision due to old age: Presbyopia Palpebr/o means: eyelid Glaucoma is primarily diagnosed by: Tonometry Myopia: Nearsightedness Combining form for cornea: kerat/o Tinnitus: sensations of noises in the ears without an external source Dizziness: Vertigo Astigmatism: defective curvature of the cornea or lens Removal of a middle ear bone: stapedectomy Modality means: method of treatment Hypoplasia of bone marrow: myelosuppression A cancerous tumor derived from bone: Osteogenic sarcoma Pharmacokinetics is BEST described as: study of the distribution and removal of drugs in the body Return of symptoms of disease: Relapse Redness of skin, often a side effect of radiation therapy: erythema Malignant tumor of fibrous tissue: fibrosarcoma Description of a fungating tumor: mushrooming pattern of growth as tumor cells pile on top of each other Replication of cells: Mitosis
