what is gas exchange
process of blood exchanging oxygen entering blood and carbon dioxide leaving
what body organ do we use to breathe?
lungs
what is it called when body temperature lowers below the usual temp
hypothermia
heart rate x stroke volume =
cardiac output
what is the main function of arteries?
carry oxygen rich blood away from heart
where does gas exchange occur in the lungs, be specific
alveoli
where about are the lungs located
chest
what is thermoregulation
your body staying at the correct temperature
stroke volume is
the amount of blood pumped per beat
3 main types of blood vessels

during this process which gas moves in and which moves out of the blood
oxygen in, carbon dioxide out
what is the basic function of lungs
