Describe how hydrogen ion secretion impacts acid-base balance
What will be an ideal response?
Renal hydrogen ion secretion is extremely important in regulating acid–base balance in the body. Hydrogen ions secreted into the tubular fluid are eliminated from the body in the urine. Hydrogen ions can be secreted by the proximal, distal, and collecting tubules, with the extent of hydrogen ion secretion depending on the acidity of the body fluids. When the body fluids are too acidic, hydrogen ion secretion increases. Conversely, when the hydrogen ion concentration in the body fluids is too low, hydrogen ion secretion decreases.
