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...
