PE - blood pressure 0.0 / 5 ? Physical Educationblood pressureASAQA Created by: bellabingbong08Created on: 12-05-16 10:24 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 10 of 10
