What muscles are most important for respiratory system

residual volume
air left in lungs after max exhale
vital capacity
amount of air we can inhale and exhale in one breath
Which side of the heart pumps oxygenated blood to the body
left
which side fo the heart pumps blood to the lungs
Right
Which chambers receive blood
atria
which chambers pump blood out of the heart

what do red blood cells carry
hemoglobin
what do platelets do
control bleeding and assist in clothing
what is the stroke bolume
amount of blood in one pump
what is the cardia output
amount of blood pumped in 1 minute
bicuspid valve
stops backflow of blood from LV to LA
aortic valve
stops backflow of blood from aorta to LV
pulmonary valve
stops backflow from pulmonary artery to RV
coronary arteries
branch from aorta where it emerges from LV
myocardium
relies on aerobic respiration, has own blood transport system
left anterior descending artery
supplied oxygenated blood to anterior LA and LV
left circumflex artery
o2 blood to posterior portion of LA and LV
right coronary artery
o2 blood to RA and RV
coronary sinus
empties deoxygenated blood from myocardium into RA to join other blood from body
