Physiology and pathophysiology of colonic motor activity

  title={Physiology and pathophysiology of colonic motor activity},
  author={Dr. Sushil K. Sarna},
  journal={Digestive Diseases and Sciences},
Major functions of the colon are to (1) absorb water, certain electrolytes, short chain fatty acids, and bacterial metabolites; (2) slowly propel its luminal contents in the caudad direction; (3) hold the residual fecal material in the distal colon until defecation; and (4) rapidly move its contents in the caudad direction during mass movements and defecation. In higher animals, defecation habits may depend on social constraints, convenience, and survival instincts. Thus, although the… CONTINUE READING
