Question
Chapter 27.2, Problem 9AYP
Summary Introduction
To analyze:
The sensory receptors that are responsible for activating neural and hormonal mechanisms to regulate extracellular fluid volume.
Introduction:
The body’s water content is regulated so that the total volume of water in the body remains constant. Thus, the volume of water taken into the body is equal to the volume lost each day. Changes in the volume of water alter the osmolality, blood pressure and interstitial fluid pressure.

Which of the following happens if the concentration of potassium in the extracellular fluid increases too much?A) Potassium would be taken up by the oligodendrocytes, so no net change in signaaaling would result. B) No signaling could occur. C) The Neuron would become hyperexcitable D) The sodium pumps would immediately fix the situation, so no net change in signaling would result.
What is the function of most intracellular receptors?
