Heptic Artery & Vein | liver |
Femoral Artery & Vein | legs |
Valves | in veins, prevent back flow |
Left Ventricle | most muscular chamber |
Blood Pressure | normal resting: 120/80 |
Hypertension | high BP: 140 and/or 90 |
Atherosclerosis | arteries harden, clog w/cholesterol |
Coronary Bypass | routes blood around clot |
Angioplasty | balloon opens artery |
Stroke | brain damage from clot or high BP |
Arrhythmia | irregular heart beat |
Electrocardiogram | heart electrical activity recorded |
SA Node | pacemaker |
AV Node & Purkinje Fibers | receive signal from SA node |
Diastole | relaxation |
Systole | contraction |
Septum | divides heart in half |
AV Valve | valve between atrium & ventricle |
