A little about the heart, blood, lymph and circulation

TermDefinition
name and function for RBC Red blood cell = erythrocyte carries oxygen to the cells of the body hemoglobin on the RBC carries the oxygen. The iron in the hemoglobin makes the blood red.
hemostasis prevention or stopping of blood loss hemo = blood stasis = "stay"
serum blood remains after formed elements AND CLOTTING FACTORS are removed
colorless disc shaped cell fragment in the blood platelet helps with clotting, has no nucleus
Fibrinogen changes to fibrin for blood clotting causes the platelets to stick together making a "plug"
What blood types are in the ABO system? O, A, B, AB Each blood type contains it's own type of anti-antigen.
A + after the letter of the blood type indicates -? The presence of the Rh factor. A person who does not have Rh factor cannot receive blood with Rh.
A - after the letter of the blood type indicates -? Rh is not present in the blood. A person who is - will agglutinate if given Rh factor. -and sometimes death.
hormone made in kidney that stimulates RBC production erythropoietin The hormone acts on the red bone marrow causing the RBCs to be made there
antigen causes a response of the immune system - will be "attacked" by anti antibodies to protect the body
antibody produced to protect the body from antigens this is an immune response to fight off a potential threat
innate immune system immune system you are born with skin, mucous, breast milk constituents, sebum, cilia, lymph nodes,
lymphocytes and monocytes WBCs higher counts indicate an infection possibly chronic or possible autoimmune response
leukocytes are WBCs; the greatest number are what type? Neutrophils 60-70% of the circulating WBCs -an immune defense against bacteria and fungi
reduction of the number of cells cytopenia penia = reduction cyto = cell
erythropoiesis erythro = RBC poiesis = formation of production of red blood cells
hypoproteinemia hypo = low protein = protein emia = blood low levels of protein in the blood
leukoblast leuko = white or clear blast = young forming cell immature WBC
myelogenous WBCs that come from marrow, not the lymph, -implicated in Chronic myeloid leukemia
hemocytometer hemo = blood cyto = cell meter = measure device that counts cells
thrombocythemia thrombo = clot cyt = cells emia = blood as in.. the body is making too many platelets and it is interfering in normal clotting
lymphopoiesis lymph = lymph poiesis = formation formation of lymph cells
thrombolysis thrombo = clot lysis = destruction destruction of a clot
myeloma mye = bone marrow plasma cell oma = tumor or cancer tumor or cancer of the bone marrow
azotemia azot, "nitrogen" + -emia, "blood condition Azotemia is an elevation of blood urea nitrogen (BUN) and serum creatinine levels
ferric ferric = relating to iron
sideroderma sidero = haemosiderin =brown spots derma = skin brown spots in the skin on the legs
hypokalemia hypo = less, lower, under kalemia = potassium blood's potassium levels are too low
anemia low hemoglobin in the blood usually iron deficient
bleeding into the skin petechiae, purpura, ecchymoses evaluated by size of the spot created in the skin
Hodgkin disease lymphoma cancer of a part of the immune system called the lymph system
allergy hypersensitivity unhealthy immune response to something that should not illicit a response
anaphylactic reaction extreme allergic reaction -and sometimes death serious, epi-pen, call 911 reaction
HDN Hemolytic disease of the newborn caused by Rh factor, mother must be treated before birth of
polycythemia poly = many cyth emia = RBC is defined as an increase in red cell mass as evidenced by increase in hemoglobin, hematocrit and number of circulating erythrocytes
complement group of enzymes active in the immune responsee
sepsis presence of microorganisms in the blood potentially life threatening
autologous blood auto = same logous = having a correspondence or relation saving blood from the client in case the client needs it later in surgery etc.
HIV & EBV viruses
Thick middle layer of the heart myocardium
septum wall
pulmonary arteries takes blood from heart to lungs
semi lunar valves aortic and pulmonary valves
superior and inferior venae cavea bring blood into the deoxygenated to the Right atrium
mitral valve valve between the left atrium and ventricle
heart murmer irregular heartsound swish sound of blood flowing
systole heart contracts
electrical impulse int he heart goes from the AV bundle to bundle of His The electrical impulse travels from the sinus node to the atrioventricular node (also called AV node). There, impulses are slowed down for a very short period, then continue down the conduction pathway via the bundle of His into the ventricles
Sphygmomanometer measures blood pressure blood pressure cuff
blood leaves the left ventricle then travels to: aorta As the atrium contracts, our left atrium into your left ventricle through the open mitral valve. ... ventricle contracts. As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body
arteries carry blood away from the heart thicker, higher pressure
veins carry blood toward the heart lower pressure than arteries, can be capacitance vessels
thoracic duct largest lymphatic vessel about 75% of lymph drains into the heart through this duct
cardioptosis cardio = heart ptosis = dropped
interventricular a term that means between the ventricles
valvotome valvo = valve tome - instrument as... (valґvo-tōm) a surgical instrument for incising a valve.
angiography angio = blood vessel graphy = graphing imaging of vessels
phlebectasia abnormal dilatation of vein an abnormal saccular or fusiform dilatation of a vein
aortostenosis aorto = aortic valve stenosis = abnormal narrowing
arteriosclerosis arterio = artery sclerosis = thickening, hardening
phlebostasis phlebo = vein stasis = slow as.... The abnormally slow motion of blood in the veins, usually with venous distention. The compression of the proximal veins of an extremity by use of tourniquets
lymphadenopathy lymph = lymph adeno = gland pathy = disease disease of the lymph nodes, in which they are abnormal in size or consistency
asplenia a = no splenia = spleen
lymphocyte cell of the lymphatic system a form of small leukocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system
lymphangioma lymph = angioma = a swelling or mass that occurs mainly in the head, neck, and mouth
thrombosis is the formation of a blood clot as... is the formation of a blood clot, known as a thrombus, within a blood vessel
anyurism weakened and bulging wall of an arterial vessel
angina chest pain signaling an MI pain resulting from coronary artery disease or heart attack
bradycardia brady = slow cardia = heart rate because tom brady is slow
MI or myocardial infarction heart attack
tackycardia faster than normal heart rate because it is tacky to be too fast or early
hemorrhoids enlarged veins of the rectum because tissues there are more delicate
where sinus rhythm originates SA node as.. normal regular rhythm of the heart set by the natural pacemaker of the heart called the sinoatrial (or sinus) node. It is located in the wall of the right atrium (the right upper chamber of the heart)
extrasystole extra heartbeat a heartbeat outside the normal rhythm, as often occurs in normal individuals.
phonocardiography high-fidelity recording of all the sounds of the heart phonocardiography is the recording of all the sounds made by the heart during a cardiac cycle
vasodilator drug used to dilate the vessels usually for lowering the pressure in the vessels and heart
CPR cardio pulmonary resuscitation
ECG electrocardiogram
AED used to correct heart rhythm
plasma blood without the formed elements formed elements are blood cells and platelets, the remaining clear liquid is plasma
