Card Set Information
blood is forced OUT of the heart
blood fills the ventricles
these collect blood
these pump blood out from the heart
right side pump deals with the
left side pump deals with the
rest of the body besides the lungs
the atria contract when (nodes)
SA to AV node
the ventricles contract when
His to Purkinje
which wave is depolarization, contraction of atria?
which wave is contraction of ventricles, depolarization?
which wave is recovery (repolarization)?
3 layers of pericardium
widening, widened blood vessel
blood clot that obstructs a vessel
when a thrombus travels through the vessels it is called
removal of innermost wall of artery
any dz that interferes with the ability of coronary arteries to deliver sufficient blood to the myocardium
coronary artery disease
area of tissue that undergoes necrosis after cessation of blood supply
PTCA: percutaneous transluminal coronary angioplasty
coronary artery bypass graft (uses vein)
small masses of fibrin and platelets from bax lodging in weakened heart tissue
enlarged, twisted superficial veins
when vein valves aren't working you get
another word for "not working" (like vein valves in varicose veins)
soft blowing sound/murmur
narrowing of a vessel (aorta)
quivering/spontanous muscle contrax causing ineffectual contrax
sense that heart is not beating normally (can include many)
when blood from the aorta goes into the pulmonary artery (because it didn't close at birth)
patent ductus arteriosis
circulation of blood through tissues
passage of fluids through vessels of an organ
reduction of the LUMEN caused by smooth muscle contraction
widening of the LUMEN caused by smooth muscle relaxation
blood flows (slowly, quickly) through capillaries
slowly--gives it time to make the gas exchange
bulge that might rupture
hollow thin mesh tube placed in artery after angioplasty to keep it open
these three are
how do cardiac enzymes help dx MI?
they do predictable things at certain intervals after MI.
endocarditis can be ____ or _____
infective (microbes) or noninfective (thrombi).
backflow of blood (through a valve when there shouldn't be)
small masses of fibrin and platelets in weakened heart tissue (because of bax)
vegetations collect on the valves, causing
what happens in varicose veins?
valves are incompetent, allows backflow, bulge
primary tumor of the heart
myxoma (mucous connective tissue)
