<prompt> A 25 year old man is paicipating in a clinical study to determine the cardiovascular response to physical exercise. Basal measurements are Respiratory rate:15,Blood pressure: 12080,Cardiac output: 5L,Hea rate:50min.What is his stroke volume during resting conditions in mLmin?5075100125  <response>: The cardiac output CO is equal to the volume of blood ejected from the hea during each systole i.e., the stroke volume; SV multiplied by the number of times the hea beats each minute hea rate; HR. In other words, CO SV x HR. Therefore, SV COHR, and since CO 5000 mLmin, and HR 50min, SV 500050 100 mL. Ref: Mohrman D.E., Heller L.J. 2010. Chapter 1. Overview of the Cardiovascular System. In D.E.
