Fluid regulation mechanisms - Answer--The thirst center. The thirst center in the hypothalamus stimulates or inhibits the desire for a person to drink. -Antidiuretic hormone. ADH regulates the amount of water the kidney tubules absorb and is released in response to low blood volume or in response to an increase in the concentration of sodium and other solutes in the intravascular fluids. -The RAAS. The RAA system controls fluid volume, in which when the blood volume decreases, blood flow t...

When discussing causes of hypernatremia (elevated serum sodium), it is correct to include: Select all that apply. A) Excessive free water intake. B) Inappropriate administration of hypertonic saline solution. C) Over secretion of the hormone aldosterone. D) Cushing syndrome. E) Ingesting large amounts of dietary sodium. (Ans-B,C,&D High sodium can be caused by inappropriate administration of hypertonic saline (sodium bicarbonate in cardiac arrest), over secretion of aldosterone, and Cu...

What makes up 1/3 of the body's water content? extracellular fluid (ECF)--15 liters Where is intracellular fluid (ICF)? Figure 13-1 inside cell membranes What are fluids used to deliver? dissolved nutrients, electrolytes, cells for immunity, and histamine Where does aldosterone come from and when is it secreted? adrenal cortex; sodium levels in ECF are too low or have dropped Why is aldosterone secreted? to prevent water and sodium loss aldosterone actions -triggers kidney nephrons to reab...

Physiology of Electrolyte Balance Study Guide Test. Which electrolyte is the principal cation in the intracellular fluid (ICF) compartment? Sodium Phosphate Potassium Calcium - CORRECT ANSWER Answer: Potassium Explanation: Sodium Sodium is the major extracellular fluid (ECF) compartment cation. Phosphate Phosphate, although found in the ICF compartment, is negatively charged; therefore, it is an anion. It is, however, the most abundant anion in the ICF compartment. Pota...
