Answer- this staement is true.
Explanation- End Diastolic volume is volume of blood present in the heart at the end of the diastole and before beginning of the atrial systole.
As heart rate increases, the heart has less time to fill during dastole. This leads to decrease in EDV.

During exercise, the filling time for the ventricles is greatly shortened, however cardiac output increases. How is this best explained? A. The increase in venous return during exercise compensates for the reduced filling time B. Stroke volume decreases but an increased heart rate compensates for it C. Stroke volume decreases but increased contractility compensates for it D. None of the above E. A and B

1. True or False (circle one): Confounding and interaction are different concepts that may occur simultaneously. 2. True or False (circle one): If interaction exists on an additive scale, it also exists on a multiplicative scale. 3. True or False? Interaction is completely reciprocal, in that if Z modifies the effect of A, then A modifies the effect of Z. 4. True or False? Sample size inevitably decreases as more strata are created in subgroup analysis, making it less...

If the heart rate increases to very high level, then Question 17 options: a) the oxygen constant of the blood falls to levels insufficient to maintain cardiac activity b) end-diastlic volume drops because ventricular filling time is so short c) end-systolic volume increases because the valves are open for only a short time d) the autonomic nervous system will release more epinephrine to the sinoatrial node to stabilize the heart rate e) stroke volume increases to keep cardiac output constant

Each time your heart beats, your blood pressure first increases and then decreases as the heart rests between beats. The maximum and minimum blood pressures are calledthe systolic and diastolic pressures, respectively. Your blood pressure reading is written as systolic/diastolic. A reading of 120/80 is considered normal. A certainperson's blood pressure is modeled by the function p(t)=115 25sin (160pit) where p(t) is the pressure in mmHg, at time t measured in minutes. a) Find the period of pb) FInd the...
