Ch. 27 test review T


Clumping together Agglutination
Anemia Condition in which levels of hemoglobin in the red blood cells are insufficient; caused by decreased healthy red cell production by the bone marrow
Aneurysm Abnormal widening or ballooning of a portion of an artery related to weakness in the vessel wall
Angioplasty Surgical vessel repair procedure frequently used to reopen a blocked coronary artery
Aorta Largest artery of the blood into which blood enters after it leaves the left ventricle
Arrhythmia Irregular heartbeat caused by a disturbance of normal electrical activity of the heart pulse with an irregular rhythm
Arteriosclerosis A thickening and loss of elasticity of the arteries also called hardening of the arteries
Atherosclerosis Narrowing and hardening of the vessels Lumen of the arteries due to a buildup of fatty material and plaque
Atria Two upper chambers of the heart
Atrioventricular Valve
Auscultation Listening to sounds within the body such as heart sounds
Bicuspid valve The valve through which the blood leaves the left atrium of the heart; also known as mitral valve.
Blood pressure Force exerted by the blood on the walls of the arteries
Bradycardia Abnormally slow heart rate or below 60 beats per minute
Bruit Sound made by a heart murmur
Buffers Mechanisms within the blood that balance the pH level does preventing blood from becoming too acidic or too alkaline
Bundle of His One of the three areas of specialized neuromuscular tissue that initiates the heartbeat also called Atrioventricular (AV) bundle
Cardiac arrest Stoppage of the beating of the heart also called sudden death
Cardiac tamponade Congestion of the heart muscle and restriction of heart movement caused by the blood or fluid trapped in the pericardial sac
Cardiogenic shock Collapse of the cardiovascular system characterized by vasodilation and fluid shifting away from the heart
Carditis Inflammation of the hearts
Carotid artery Artery found on each side of the neck
Congestive heart failure CHF Heart cannot pump sufficient blood to the other organs also called heart failure
Coronary arteries Crown of arteries that supply the heart with freshly oxygenated blood
Coronary artery disease CAD Blockage of the arteries that supply the heart muscle also called coronary heart disease CHD
Cor Pulmonale Heart disease that causes the right ventricle to enlarge as a result of primary lung disease also called right sided heart disease
Cyanosis Bluish discoloration of the skin and nail beds due to lack of oxygen in the tissues
Diastolic blood pressure Lowest cuff pressure at which the korotkoff sounds disappear when the left ventricle of the heart relaxes
Dyspnea Difficulty breathing
Endocardium Innermost lining of the heart wall
Erythrocytes Biconcave cells produced in the red bone marrow that are small enough to pass through capillaries and carry oxygen to the tissue and organs also called RBC's
Heart Four chambered muscular pump that circulates blood throughout the cardiovascular system
Heart murmur Condition in which a damaged or diseased valve allows blood to escape and move backward through the valve
Hemoglobin Iron containing pigment of red blood cells that carries oxygen from the lungs throughout the body
Hemophilia Hereditary deficiency of clotting factors
Homeostasis Stoppage of bleeding as a result of the smooth muscle at the side of the brake causing the vessel wall to contract creating a spasm that reduces the amount of blood loss and initiating the attachment of platelets to the broken area and to each other which
Hypertension htn High blood pressure
Hypotension Low blood pressure
Hypoxia Insufficient oxygen supply to the tissues that cause by ischemia and infarction
Infarction Death of heart muscle
Inferior venacava Large vein that brings blood from below the heart to the atrium
Ischemia Reduced blood flow to the heart
Leukemia Malignant cancer of bone marrow and blood affecting the white blood cells
Leukocyte Two types phagocytes and lymphocytes of large blood cells that fight infection and thus contributing to homeostasis white blood cells
Mitral valve The valve through which blood leaves the left atrium of the heart also called bicuspid valve
Myocardial infraction Condition that occurs when the blood supply to a part of the myocardium is severely reduced or stopped also called heart attack
Myocardium Middle muscular layer of the heart
Occlusion Blockage
Pericardium Outer lining of the heart wall
Petechiae Tiny broken blood vessels on the surface of the skin
Plasma Fluid portion of the blood water portion of the blood that contains blood cells
Platelets Smallest cells in blood formed in the red bone marrow main function is to assist in the clotting of the blood for wound healing also called thrombocytes
Prehypertension In adults over 18 years old blood pressure ranging from 120/80 to 139/89 mmHg, considered a precursor to hypertension
Pulmonary artery Artery that transports blood from the right ventricle to the lungs
Pulmonary vein Vein that transports freshly oxygenated blood from the lungs to the left atrium
Pulse pressure Difference b/w the systolic and diastolic blood pressure
Purkinje fiber Specialized conductive fibers located within the walls of the ventricles responsible for relaying cardiac impulses to the cells of the ventricles which then contract
RhoGam Drug administered to a pregnant woman to inhibit the production of antibodies against the RH antigen
Septum Wall that separates the left and right sides of the heart
Sinoatrial SA node One of the three areas of specialized neuromuscular tissue that initiates the heartbeat located in the upper wall of the right atrium also called pacemaker of the heart
Sphygmomanometer Instrument used to measure blood pressure
Stroke Results of a clot or Hemorrhage in the brain clocking the blood supply in causing brain cells to die from lack of oxygen
Superior venacava Large vein that transports blood from the head and upper chest to the heart
Systolic blood pressure Upper number of blood pressure measurement indicated of the left ventricle of the heart Contracting
Tachycardia Abnormally rapid heart rate
Thrombophlebitis Condition that occurs when the blood clot causes inflammation in one or more veins typically those of the lower extremities
Tricuspid valve Heart valve from the right atrium to the right ventricle
Venipuncture The process of cutting into or puncturing of Maine typically for the purpose of collecting blood samples for testing
Ventricles Small blisters
