| A | B |
|---|
| Artery | away from heart |
| Vein | toward heart |
| Capillary | exchange with tissues |
| Pulmonary Circuit | heart to lungs & back |
| Systemic Circuit | heart around body & back |
| Atria | top of heart, blood enters |
| Ventricles | bottom of heart, blood exits |
| Heart Chambers | four |
| Aorta | largest artery, exits left ventricle |
| Inferior Vena Cava | from lower body to right atrium |
| Superior Vena Cava | from upper body & head to right atrium |
| Pulmonary Artery | right ventricle to lungs |
| Pulmonary Vein | lungs to left atrium |
| Coronary Arteries | blood to heart tissue |
| Carotid Arteries | blood to head & neck |
| Jugular Veins | blood from head & neck |
| Brachial Artery | blood to arms & hands - BP location |
| Renal Artery & Vein | kidneys |
| 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 |
| Semilunar Valve | valves for aorta & pulmonary trunk |
| Cardiac Cycle | complete heart beat - "lub dup" |
| Pulse | normal resting: 60-70 beats per minute |
