circulatory system Flashcards
myocardium
cardiac muscle that forms the heart
pulmonary circulation
function of the right side of the heart is to pump deoxygenated blood to the lungs
systemic circulation
the role of the left side of the heart is to pump oxygenated blood to the rest of the body
arteries
blood vessels that carry blood AWAY from the heart
veins
blood vessels that carry blood TOWARDS the heart
arterioles
small blood vessels that carry blood away from your heart
capillaries
connection between the vessels that carry blood away from the heart and the vessels that return blood to the heart
systolic blood pressure
maximum pressure observed in the arteries during the contraction phase
diastolic blood pressure
minimum pressure observed in the arteries during the relaxation phase
bradycardia
a heart rate of 60 beats per minute or less at rest
tachycardia
a heart rate of more than 100 beats per minute at rest
cardiac output (q)
the volume of blood pumped out of the left ventricle in one minute
stroke volume (sv)
the amount of blood that is ejected from the left ventricle in a single beat
heart rate (hr)
the number of times the heart contracts in a minute
how to calculate cardiac output
Q = SV x HR
