Question | Answer |
---|---|
endothelium | membranous tissue that lines the heart and blood vessels |
SA nod, AV node, AV bundel, Purkinje fibers | order in which an impulse passes through the conduction system of the heart |
chordate tendineae are attached to the | tricuspid valve |
Fibrous pericardium | tough, loose-fitting, inelastic sac around the heart |
Mitral valve prolapse | flaps extend back into the left atrium |
systole | heart contracting |
diastole | heart relaxing |
pericardium | heart covering 2 layers fibrous tissue with space |
visceral pericardium / epicardium | inner layer of pericardium |
parietal pericardium | fits around heart like loose sac |
myocardium | heart chamber cardiac muscle |
Ateria | receiving chamber of heart |
ventricles | discharging chambers of heart |
endocardium | thin layer of very smooth tissue lining heart chambers |
Vein | carries blood back to the heart, has valves, reservoirs for blood |
Artery | carries blood away from heart, thicker tunica media, |
aneurysm | section of an artery that has become abnormally wide because of a weakening of the arterial wall |
hepatic portal circulation | receives blood from stomach, spleen and intestine, detoxicate blood, blood passes thru second capillary bed |
CVA cerebrovascular accident | brain aneurysm, stroke |
ischemia | decreased blood supply to a tissue |
necrosis | complete tissue death |
gangrene | progressed necrosis, tissue decay |
pulmonary vein | blood vessel returns blood to the left atrium |
inferior & Superior vena cava | blood vessel returns blood to the right atrium |
pulmonary artery | blood vessel receives blood from the right ventricle. |
The aorta | blood vessel receives blood from the left ventricle. |
venules | Microscopic vessels that carry blood from small arteries to small veins |
tunica externa | layer of blood vessels that is made up of connective tissues fibers to reinforce the blood vessel wall |
tunica media | layer of blood vessels that contains smooth muscle |
tunica intima | layer of blood vessels that is made up of a single layer of squamous epithelium |
foramen ovale | structure in fetal circulation shunts blood directly from the right atrium to the left atrium |
ductus arteriosus | structure in fetal circulation connects the aorta and the pulmonary artery. |
ductus venosus | structure in fetal circulation shunts blood away from the immature liver |
Neurogenic shock | shock is caused by an imbalance in the autonomic stimulation of the tunica media |
Anaphylactic shock | type of shock is caused by an acute allergic reaction. |
