| -penia | abnormal reduction in number |
| -sclerosis | hardening |
| brady- | slow |
| tachy- | rapid, fast |
| anemia | disease in which there is a reduction in the amound of hemoglobin in the RBC's; anemia may be caused by blood loss or decrease in production or increase in destruction of red blood cells |
| aneurysm | condition in which there is a ballooning of a weakened portion of an arterial wall |
| blood pressure | pressure exerted by the blood against the blood vessel walls; a blood pressure measurement written as systolic pressure (120) and diastolic pressure (80) is commonly recorded as 120/80 mm Hg |
| cardiac characterization | diagnostic procedure performed by passing a catheter into the heart through a blood vessel to examine the condition of the heart and surrounding blood vessels; used most frequently to evaluate chest pain and coronary artery disease |
| cardiopulmonary resuscitation | emergency procedure consisting of artificial ventilation and external cardiac massage |
| complete blood count | laboratory test for basic blood screening that measures hemoglobin, hematocrit, red blood cell number, size and shape, leukocyte count and white blood cell differential; this easy and rapid test provides a tremendous amount of info about the blood |
| BP | blood pressure |
| CPR | cardiopulmonary resuscitation |
| CBC | complete blood count |
| congestive heart failure | condition in which there is an inability of the heart pump enough blood through the body to supply the tissues and organs with nutrients and oxygen |
| CHF | congestive heart failure |
| coronary artery bypass graft | surgical technique to bring a new blood supply to heart muscle by detouring around clocked arteries |
| CABG | coronary artery bypass graft |
| coronary artery disease | a condition that reduces the flow of blood through the coronary arteries to the myocardium, denying the heart tissue of sufficient oxygen and nutrients to function fully (Heart failure HF) |
| CAD | coronary artery disease |
| embolism | sudden blocking of an artery by foreign material, such as air or fat, that enters the bloodstream and moves until it lodges at another point in the circulation |
| hemorrhage | rapid loss of blood, as in bleeding |
| hypertension | blood pressure that is above normal (greater than 140/90 mm Hg) |
| hypotension | blood pressure that is below normal (less than 90/60 mm Hg) |
| leukemia | malignant disease characterized by excessive increase in abnormal white blood cells formed in the bone marrow |
| myocardial infarction | death of a portion of the myocardium caused by lack of oxygen resulting from an interrupted blood supply (also called heart attack) |
| pulse | the number of times per minute the heartbeat is felt on an arterial wall; the pulse rate is most commonly felt over the radial artery; however, the pulsations can be felt over a number of sites, including the fermoral and carotid arteries |
| sphygmomanometer | device used for measuring blood pressure |
| stethoscope | instrument used to hear internal body sounds; used for performing auscultation and blood pressure measurement |
| MI | myocardium infarction |
| varicose veins | condition demonstrated by distended or tortuous veins usually found in the lower extermities |
| venipuncture | a procedure used to puncture a vein to remove blood, instill a medication, or start an intravenous infusion |
| arteries | blood vessels that carry blood away from the heart |
| blood | fluid circulated through the heart, arteries, capillaries, and veins; composed of plasma and formed elements such as RBC, WBC, and platelets |
| blood vessels | tubelike structures that carry blood throughout the body, including arteries, veins, and capillaries |
| capillaries | microscopic blood vessels; materials are passed between blood and tissues through capillary walls |
| heart | muscular, cone-shaped organ the size of a fist, located behind the sternum and between the lungs; pumping action circulates blood throughout the body |
| plasma | clear, straw-colored, liquid portion of blood in which cells are suspended; approximately 90% water and comprises approximately 55% of total blood volume |
| veins | blood vessels that carry blood back to the heart |
| lymph | transparent, colorless tissue fluid; contains white blood cells and flows in a one-way direction to the heart; similar to plasma |
| lymph nodes | small, spherical bodies composed of lymphoid tissue; may be singular or grouped together along the path of lymphatic vessels; filter lymph to keep bacteria and other foreign agents from entering blood |
| lymphatic vessels | transport lymph from body tissues to the chest; similar to veins |
| spleen | lymphatic organ located in the upper left abdominal cavity between the stomach and the diaphragm; filters blood and acts as a blood reservoir |
| thymus | lymphatic organ with two lobes located behind the sternum between the lungs; plays an important role in development of the body's immune system, particularly from infancy to puberty |
