PE - blood pressure

HideShow resource information
what is blood pressure related to
cardiac out put and resistance to flow
1 of 10
what is cardiac output
the volume of blood ejected from the left ventrical per minuite
2 of 10
what is resistance to flow
the friction between the blood and the walls of blood vessels
3 of 10
how do you calcualte blood pressure -- what does it mean in relation to raisng blood pressure
blood pressure = cardiac output X resistance -- blood pressure increases when either cardiac output resistance increases
4 of 10
why is blood pressure different in variouse blood vessels
because it is largely dependent on the distance of the blood vessels from the heart
5 of 10
what is the top and bottom reading on a blood pressure reading --- what is an average reading
systolic = top -- diastoilc = bottom -- average = 120/80
6 of 10
name 3 things that friction depends on
smoothness of the lining of the vessels -- diameter / length of the vessels -- viscosity/ thickness of the blood
7 of 10
what happens to blood pressure readings during aerobic exercise
systolic pressure increases = result of increased cardiac output -- diastolic pressure remains constant
8 of 10
what happens to the diastolic reading of a well trained athlete during aerobic exercise
it will drop as a result of blood feeding in to working muscles
9 of 10
what happens to blood pressure isometric / anaerobic exercise
pressure raise alot = due to increased resistance of the blood vessels
