Document Summary
Water and electrolyte intake and output are regulated through hormonal and neural interactions. Most metabolic processes in the body result in the production of acid. Acid is removed through the lungs (co2) and kidney (acid/base balance)***exam question!! 3 na out to ecf/ 2 k in, which goes against the concentration gradient (since na+/k atpase requires energy) makes sense why the fluid inside the cell has higher k. (potassium is pumped inside against the concentration gradient. 2 inside-- when if there was no energy it would want to leak out due to the concentration gradient). Caution: diuretics and bp meds can create an electrolyte imbalance. It helps reabsorb na + water (while excreting k+). Hyponatremia - decreased levels of sodium in the blood (less than 135meq/l) Can be caused by excessive sweating, vomiting/diarrhea, cirrhosis (i. e. a long distance runner). Need to intake electrolytes/sodium because if you just drink water, you will only dilute the salt even more.
