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
