Question
Chapter 15.3, Problem 7CC
Summary Introduction
To determine: The effect of increase in K+ ions on the blood flow in the muscles.
Introduction: The skeletal muscles are those muscles that are either connected to the skin or the skeleton or to both of the organs. These muscles help in movement of the skeletal system. It also helps in maintaining the body posture.

Every cell in the body requires oxygen for respiration so that sufficient energy can be produced. Carbon dioxide a waste product in the process, is also produced and needs to be removed from the cells. Therefore, the levels of both gases should be regulated. How does this physiological mechanism explain the changes observed and noted in the increase of pulse rate during running?
there is a known cause of high blood pressure that occurs because of a reduced fluid flow that triggers RAAS and Na+ reaborption with increased blood volume and pressure. what is it?
Consider the effect of a twofold increase in the ECF concentration of Na+ or K+ ions. Which increase in ion concentration is the more deadly and why?
Hint: Consider if the calculated decrease in or the increase in bring the resting membrane potential of the nerve or muscle cell closer to threshold potential? Why would this change in ion concentration stop the heart from beating?
