Question
Chapter 17, Problem 15CYU
Summary Introduction
To review:
The reason for the increased HR (heart rate) and SV (stroke volume) after running fast for a while.
Introduction:
Heart rate is defined as the number of times the heart beats in a unit time. A normal person should have a heart rate between 60 to 100 BPM (beats per minute). The SV is defined as the amount of blood whichis pumped out through the ventricle after a contraction. The normal person should have the SV of 50mL (milliliters) to 120mL.
