| Question | Answer |
|---|---|
| L Ventricle | Thickest wall because it needs to pump out to body |
| Stroke Volume | amount of blood pumped by each ventricle per beat |
| Heart Rate | # of beats per minute |
| Cardiac Output | amount of blood pumped out of ventricles per minute |
| Venous Return | amount of blood returned to heart per minute |
| Bicuspid Valve | between L atria and L ventricle to prevent blood return to R atria |
| Tricuspid Valve | betewen R atria and R ventricle to prevent blood return to R atria |
| Aortic Semi-Lunar Valve | between L ventricle and aorta closes when pressure in aorta is greater than relaxed ventricles |
| Pulmonary Semi-Lunar Valve | between R ventricle and pulmonary valve close when pressure in trunk is greater than relaxed ventricles |
| SA Node | initiates action potential located in upper posterior wall of R atrium |
| AV Node | Slows cardiac impule to ensure both atrial have contracted and ventricles are filled located on floor of R atrium |
| Bundle of His | only communication between atria and ventricles located interventricular septum |
| Purkinjie Fibers | Gets ventricles to contract located deep in wall of ventricles |
| LUBB | AV Valve close |
| DUBB | Semi Lunar valves close |
| Atrial Systole | Ventricles in diastole (filling) |
| Atrial Diastole | Ventricles in Sytole (draining) |
| Ventricular Systole | Atia in diastole (filling) |
| Ventricular Diastole | Atria in sytole (draining) |
| P-Wave | Atria contracting |
| QRS Complex | ventricles contracting |
| T-Wave | Ventricles relaxing |
| Coronary Arteries | veins that supply heart with blood |
| Veins | return blood to heart |
| Arteries | carry blood away from heart |
| External Jugular Vein | Drains face, scalp and neck |
| Internal Jugular Vein | Main vein drains brain |
| Pulmonary Artery | carries deoxygenated bloos from R ventricles to lungs |
| Pulmonary Vein | carries oxygenated blood from lungs to R ventricles |
| Carotoid Artery | Blood from Head to neck |
| Vertebral Artery | blood to vein and back of neck |
| Saphenous Vein | Longest vein drains foot on medial leg |
| Renal Artery | drains kidneys |
| Common Iliac Artery | Pubic region blood to organs |
| Longest artery | Aorta |
| Largest Vein | Vena Cava |
| Ductus Venous | Bypass liver to inferior Vena Cava |
| Ductus Arteriosus | bypass fetus lungs |
| Foramen Ovale | hole for blood to flow from R atrium to L atrium |
| Vena Cava | blood vessel where blood pressure is lowest |
| Capillary | where blood flows slowest |
| Baroreceptors | wall of aorta and carotoid sinus detects changes in blood pressure carries info to heart and blood vessels |
