Heart and Blood

Heart and Blood Study Sheet

2 Types of lymphotctes B lymphocytes -> secrete chemical compounds. T lymphocytes -> directly attacking bacteria or canerous cell.
AED Automatic External Defibrillators -> small light weight devices that detect a person's heart rhythem using small electrode pads placed on the torso. Doesn't require training.
Aggulutination Antibodies causing antigens to clump or stick together
Angina pectoris Servere chest pain, resulting when the myocardium is deprived of sufficent oxygen.
Aorta main and largest artery in the body
Apex of the heart blunt point of the heart, where you can hear the heart, sits on the dyhphram, inferer part of the heart.
Aplastic anemia blood disorder characterized by a low red blood cell count, caused by destruction of myeloid tissue into the bone marrow (caused by raditation therapy or toxic chemicals)
Arteriosclerosis hardening of arteries, materials such as lipids accumulate in arterial walls, often becoming hardened via calcification
Atherosclerosis hardening of arteries in which lipids (fat) and other substances build up on the inside wall of blood vessels.
Atria two upper chambers of the heart/ Recieving chamber
Basophill (Grandular WBC) inflammatory response & heparin secrection/ white blood cell that stains readily with basic dyes
Blood flow through the heart Right atrium -> Tricuspid valve (right atrioventricular) -> Right ventricle -> Plumonary semilunar valve -> lungs -> Pulmonary veins -> Left atrium -> Biscupid/Mitral/Left atrioventricular -> Left ventricle ->aortic semilunar valve -> Aorta -> Body
Blood plasma Liquid (extracellular part of blood or blood minus its formed elements)
Blood serum plasma minus its clotting factors, such as fibrinogen & prothrombin
Blood types (type A) ABO system Type A -> type of antigen (protein) in plasma membrane of you RBC's (red blood cells) that has been present since birth, plasma doesn't contain anti-A antibodies but contains anti-B antibodies
Blood types (type B) Type B -> the RBC's contain type B antigen & the plasma contains anti-A antibodies
Blood types (type AB) Type AB -> the RBC's contain both type A & type B antigens & the plasma contains neither anti-A nor anti-B antibodies
Blood types (type O) Type O -> its RBC's contain neither type A nor type B antigens & its plasma contains both anti-A and anti-B antibodies
Bradycardia slow heart rhythem-> less than 60 beats per minute
Calcium if normal amount of blood calcium is present, prothrombin activator triggers the next step of clotting by converting prothrombin to thrombin
Cardiac tamponade compressions of the heart caused by fluid buildup in the pericardial spacem as in pericarditis or mechanical damage to the pericardium
CHF Congestive Heart Failure -> left side heart failure
Diastole relaxation of the heart
Dysrhythmia any abnormality of cardiac rhythem
Embolus a blood clot or other substance that is moving in the blood and may block a blood vessel. Find in cordinary artries results in mycoardical infraction
Eosinphil (Granular WBC) defense against parasites & worms/ white blood cell that is readily stained by eosin
Erythroblastosi Rh antibodies reacting with Rh-positive RBC's characterized by massive agglutenation of the blood and resulting in life-threatening cirulatory problems
Fibrillation condition in which individual muscle fibers or small groups of fibers contract asynchronously with other muscle fibers in an organ, producing no effective movement
Fibrin insolubule protein in clotted blood
Granulocyte presence of granules. They are Neutrophils, Eosinophils, and Basophils.
Heart valve disorders Incomplete Valves Rheumatic Heart Disease Mitral Valve Prolapse/MVP Stenosed Valves
Hermatocrit volume percent of red blood cells in whole blood
Hemoglobin in RBC carries.. oxygen -> the exchange of oxygen and carbon dioxide between the blood and the body's cells and it's role in maintenance of acid-bas balance are among the most vital
Hemolytic anemia any of group of blood disorders characterized by deficient or abnormal hemoglobin that causes deformation and fragility of red blood cells
Hemorrhagic anemia group of conditions characterized by low oxygen-carrying capacity of blood; caused by decreased red blood cell (RBC) life span and/or increased rate of RBC destruction
Heparin (PREVENTS CLOTS/ BLOOD THINNER) naturally occuring substance that inhabits formation of a blood clot, used as a drug to inhibit clotting
Lymphocyte one type of white blood cell
Mitral valve heart valve located between the left atrium, causing incompetence of the valve (only 2 cusp)
Monocyte (IN TISSUE) largest type of white blood cell, a type of agranular leukocyte; often involved in phagocytosis of abnormal cells or particles
Macrophages (IN BLOOD) phagocytic cell in immune system
Myocardical infarction heart attack -> (tissue dies, part of the muscle dies) death of cardiac muscle cells resulting from inadequate blood supply as in coronary thrombosis
Neutrophil (Grandular WBC) immune defense (take them in their own bodies and digest them in the process of phagocytosis)
Nutrients requirred to manufacture hemoglobin Iron (Fe)-> essential (gives hemoglobin its oxygen-carrying ability) Vitamin B12 and Folate -> manufactures the amount of hemoglobin to maintain survial
P-Wave occurs with depolatization of the atria
Pericarditis condition in which the pericardium becomes inflamed
Pericardium membrain that surrounds the heart
Pernicious anemia (Deficiency type) results from a dietart deficiency of vitamin B12 or form the failure of stomach lining to produce "instrinsic factor" - the substance allows vitamin B12 to be absorbed
Plasma proteins any of several proteins normally found in the plasma; includes albumins (retain water in blood), globulins(protect against infection), and fibrinogen & prothrombin (helps with blood clotting)
Prothrombin a protein present in normal blood that is required for blood clotting
Rh positive the RBC's of this blood type contain an antigen call Rh factor
Rh negative the RBC's do not have the Rh antigens on their surfaces
Semilunar valves valves located between the 2 ventricular chambers and the large arteries that carry blood away from the heart,valves found in the veins (kinds are Pulmonary-in & aortic- out) last gate keeper/dub sound valves closing cuz blood flow through ventricles
Sickle cell anemia (hemolytic anemia type) severe, possibly fatal, hereditary disease caused by an abnormal type of hemoglobin
Stroke Volume the amount of blood that is ejected from the ventricles of the heart with each beat
Superior vena cava one of two large veins returning deoxygented blood to the right atrium
Inferior vena cava one of two large veins carrying blood into the right atrium
Systole contraction of the heart muscle
T-Wave results from electrical activity generated by repolarization of the ventricles
Tachycardia rapid heart rhythm -> more than 100 beats per minute
Thalassemia (hemolytic type) any group of inherited hemoglobin disorder characterized by production of hypochromic, abnormal red blood cells
Thrombocyte blood cells that play a role in blood clotting, also called platelets
Thrombus stationary blood clot
Tissue plasminogen activator/ TPA (TAKE ONLY IF YOU HAVE A CLOT) naturally occurring substance that activates plasminogen & converts it to the active enzyme plasmin, which in turn dissolve fibrin blood clots
Tricusoid valve (right artioventricular valve the valve located between the right atrium and ventricle (only 3 cusp)
Universal donor blood type O
Ventricles small cavities
Caridac output volume of blood pumped per minute
Perocardium visceral pericardium/epicardium- inner layer partietal pericardium- outter layer(sac)
Nongranular WBC lymphocytes & monocytes
Stenosed Valves are narrower than normal
Incomplete valves leaks allowing blood to flow back into the chamber from which it came
Rheumatic heart disease cardiac damage resulting from a delayed inflammatory response to streptococcay infection (occur most in children)
Mitral valve prolapse/MVP condition affecting the biscupid valve has a genetic basis in some cases but can result from rheumatic fever or other factors
