layer of bundled cardiac cells that contract
interventricular septum
wall of muscle separating ventricles
atrioventricular valves
valves between each atria and ventricle

valve between right atrium and ventricle
bicuspid valve
valve between left atrium and ventricle
semilunar valves
valves between ventricles and corresponding arteries
pulmonary valve
valve between right ventricle and pulmonary artery
aortic valve
valve between left ventricle and aorta
tunica intima
layer of a blood vessel that has epithelial tissue
tunica media
layer of a blood vessel that has smooth muscle and elastic tissue
tunica externa
layer of a blood vessel that has fibrous tissue
precapillary sphincter
smooth muscle that opens and closes the capillary
vascular shunt
direct pathway from arteriole to venule through capillary bed
lymphatic system
system that reclaims fluid leaked by capillaries
sinoatrial node
pacemaker of the heart
atrioventricular valve
node that slows pauses electrical impulse
lub
sound made when atrioventricular valves close
dub
sound made when pulmonary and aortic valves close
systolic
highest pressure
diastolic
lowest pressure
cardiac output
amount of blood pumped each minute for each ventricle
peripheral resistance
friction between blood and tunica intima
brachial artery
artery used for taking blood pressure in adults
femoral artery
artery used for taking blood pressure in infants
medulla oblongata
area in brain where information about blood pressure is sent
baroreceptors
type of mechanoreceptor located in the aortic arch that senses and relays blood pressure information to the brain
sympathetic nervous system
nervous system that prepares you for exercise
parasympathetic nervous system
nervous system that returns body back to normal after exercise
hypertension
high blood pressure
atherosclerosis
blockage of arteries through buildup of plaque/cholesterol
