cardiovascular system Flashcards
main functions of CV system
transport of o2 nutrients and metabolites to tissue
distribution of hormone to tissue
involvment in homeostatic mechanics
how is the systemic circulation connected
in parallel which means that there is a choice of which part of the body recieves more or less of the available blood
how is the pumonary circulation connected
in series which means that the entire blood volume has to pass though it every time it circuates
how much blood does the average person have
5 liters of blood 7% of body weight
what is the average cardiac output
5liters per minute
what does contraction of ventricles generate
generates pressure which is transferred to the blood causing it to flow along the blood vessels
what does flow concern
the pressure difference, not the absolute values in pressure
what does higher driving pressure and larger vessel radius cause
higher flow
the narrower the vessel the …
faster the flow
