Strenuous exercise can increase cardiac output by how many times the resting level?
In strenuous exercise, how many times can blood flow through a skeletal muscle increase from the resting perfusion?
Complete the equation: Cardiac Output (CO) =
In acute exercises, what results in increases in heart rate and stroke volume (and therefore cardiac output)?
What is a positive inotropic effect (a result on the heart muscle from increased sympathetic stimulation)?
What is a positive chronotropic effect (an effect on the heart as a result of increased sympathetic stimulation)?
At rest, what percentage of the blood volume is found in the venous circulation (particularly the large/capacitance vessels)?
What causes venoconstriction during exercise?
Other than venoconstriction and the muscular/respiratory pumps, what helps shift blood from the venous side to the arterial side of the circulation?
Describing the relationship between the heart and the circulation in determining blood pressure, complete the equation: Mean Blood Pressure (MBP) =
Mean Blood Pressure = Cardiac Output x Total Peripheral Resistance. If CO can increase by 500% in strenuous exercise, but MBP may only increase by less than 50%, and there is vasoconstriction and more blood shifted to the arterial circulation...how is it that TPR does not increase but must in fact decrease for MBP = CO x TPR to be true>
As a generalisation, systolic pressure can be viewed as dependent on...
Generally, diastolic pressure is determined by...
At which intervals were measurements for blood pressure and heart rate taken?
What equipment was required for this lab?
