| 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. |
