cardiovascular system | chapter 5 |
angi/o | blood, lymph vessels |
aort/o | aorta |
arter/o, arteri/o | arteries |
ather/o | plaque, fatty substance |
brady- | slow |
card/o, cardi/o | heart |
coron/o | coronary, crown |
-emia | blood, blood condition |
erythr/o | red |
hem/o, hemat/o | blood, relating to blood |
leuk/o | white |
phleb/o | vein |
tachy- | fast, rapid |
thromb/o | clot |
ven/o | vein |
pericardium | double-walled mambranous sac that encloses heart |
pericardial fluid | between layers, prevents friction |
epicardium | external layer, also part of pericardium |
myocardium | middle and thickest layer |
endocardium | lining of heart, inner surface |
atria | 2 upper receiving chambers |
interatrial septum | separating wall |
ventricles | 2 lower thicker walled chambers, all vessels leave heart from here |
interventricular septum | separating wall |
tricuspid valve | TV, 3 point opening between R atrium and R ventricle |
pulmonary semilunar valve | half moon opening between R ventricle and pulmonary artery |
mitral valve | MV, bicuspid, 2 point opening between L atrium and L ventricle |
aortic semiluna valve | half moon shaped opening between L ventricle and aorta |
systemic circulation | blood flows to all point except lungs, o2 rich goes out L ventricle into arterial circulation, o2 poor comes in R atrium from veins |
pulmonary circulation | blood flows between heart and lungs, o2 poor goes out R ventricle to pulmonary arteries to lungs, o2 rich comes in L atrium from pulmonary veins |
sinoatrial node | natural pacemaker, posterior wall of R atrium, starts contraction of both atria forcing blood into ventricles |
atrioventricular node | on floor of R atrium, transmits electric umpulses to bundle of his |
bundle of his | within interventricular septum, carries impulses to purkinje fibers causing ventricles to contract forcing blood into aorta adn pulmonary arteries |
lumen | opening within arteries, capillaries, and veins |
arteries | carry o2 rich blood from heart to all points |
aorta | main trunk, begins from L ventricle |
coronary artery | branches from aorta, supplies blood to myocardium |
arterioles | smaller thinner branches, carry blood to capillaries |
capillaries | smallest vessels in body, connect arterial and venous circulatory systems, exchange o2, nutrients, and waste materials |
veins | return waste filled blood to heart, thin walled with valves for 1 way flow, venules small veins join up to make larger vein |
venae cavae | 2 large veins that enter heart |
superior vena cava | brings blood from upper portion of body |
inferior vena cava | brings blood from lower portion of body |
blood pressure | systolic- ventricles contract, highest pressure, diastolic- ventricles relax, lowest pressure |
blood composition | 55% liquid plasm, 45% formed elements (blood corpuscle) |
blood corpuscles | red and white blood cells, platelets |
plasma | straw colored, contains nutrients, hormones, waste products, water, proteins, and clotting proteins |
serum | plasma with clotting proteins removed |
fibrinogen and prothrombin | clotting proteins |
erythrocytes | mature red blood cells |
hemoglobin | iron containing pigment that transports o2 from lungs to all points |
reticulocyte | immature erythrocyte with meshlike pattern of threads |
macrophanges | from spleen,liver, and bone marrow destroy erythrocytes after no longer useful 120 days |
leukocytes | white blood cells, protects body from harmful bacteria |
neutrophils | fight infection by phagocytosis, most common of WBC, indicate bacterial infection |
phagocytosis | process of engulfing and swallowing germs |
basophils | promote inflammatory response, indicate allergic condition |
eosinophils | increase in reponse to allergic reaction |
lymphocytes | protect body against disease |
monocytes | protect against disease, indicates chronic infection |
trombocytes | platelets, fragments of large bone marrow cells called megakaryocytes, become sticky and form clots |
cardiologist | specializes in diagnosing and treating abnormalities, diseases and disorders of heart |
hematologist | specializes in diagnosing and treating diseases adn disorders of blood and blood forming tissues |
coronary artery disease | CAD, atherosclerosis of coronary arteries, cause angina pectoris, myocardial infarction, and death |
end stage CAD | unrelenting angina pain and severly limited lifestyle |
isch- | hold back |
ischemia | deficiency in blood supply |
angina pectoris | choking/suffocating chest pain caused by interference of o2 to myocardium |
infarct | localized area of necrosis caused by interruption of blood supply |
prolapse | falling down |
cardiac arrhythmia | dysrhythmia, irregularity or loss of normal rhythm |
fibrillation | rapid, random, and ineffective contractions of heart |
perfusion | flow of blood through the vessels of an organ |
aneurysm | localized weak spot, balloon-like enlargement of wall of artery, ruptures often fatal |
thrombus | blood clot attached to interior wall of vein or artery |
occlusion | blockage in canal, vessel, or passageway |
embol | something inserted |
embolus | foreign object, blood clot, air, gas, tissue, or tumor, circulating in blood |
embolism | blockage of vessel by embolus |
-crasia | mixture, blending |
chromat/o | color |
hemochromatosis | iron overload disease |
septicemia | blood poisoning |
cholesterol | lipids (fatty substances) travel in packages called lipoproteins |
low-density lipoprotein cholesterol | LDL, bad, contribute to plaque buildup |
high-density lipoprotein cholesterol | HDL, good, doesn't contribute to plaque buildup |
triglycerides | combination of fatty acids attached to glycerol found normally in blood in limited quantities |
homocysteine | amino acid normally found in blood, used to build tissue, high levels can damage arterial walls and increase rick of CAD |
-penia | deficiency |
plast/o | growth, mold |
-lytic | destroy |
essential hypertension | primary, idiopathic, unknown origin |
secondary hypertension | caused by different medical problem, when other problem cured hypertension should resolve |
percutaneous transluminal coronary angioplasty | balloon angioplasty |
coronary artery bypass graft | CABG, bypass surgery, vein from leg implanted on heart to bypass blockage in coronary artery |
minimally invasive direct coronary artery bypass | MIDCABG, keyhole/buttonhole bypass |
defibrillation | cardioversion, use of electric shock to restore hearts normal rhythm |
cardiopulmonary resuscitation | CPR |
-stasis | stopping, controlling |
plasmapheresis | plasma is removed from blood then returned to donor, to reduce/eliminate harmful substances |
