MEDICAL PHYSIOLOGY

Detailed explanation-1: -The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.

Detailed explanation-2: -Water and electrolyte absorption primarily occurs in the small and large intestines. Dysregulation of this absorption can either lead to diarrhea or constipation.

Detailed explanation-3: -The bulk of the transport of these fluids and electrolytes occurs through the small intestine, leaving approximately 1.5 L for the colon to absorb and leaving approximately 100 mL that is lost through the stools every day.
