Some digestive and gastrointestinal disorders are associated with genetic abnormalities
- cleft lip and/or palate- familial adenomatous polyposis- hereditary nonpolyposis colorectal cancer (HNPCC)- hirschsprung disease (aganglionic megacolon)- IBD (crohn's disease)- Pyloric stenosis
Colonic function:
- bacteria (in large intestine) helps complete breakdown of waste material: undigested or unabsorbed proteins and bile salts
Colonic secretion: ELECTROLYTE SOLUTION
(bicarbonate solution) neutralizes the end products formed by colonic bacterial action
Colonic secretion: MUCUS
Protects the colonic mucosa and provides adherence for fecal mass(damaged mucus can = damage to blood vessels)
Primary function of colon:
Slow transport to allow efficient reabsorption of water and electrolytes (allowed by: slow, weak peristalsis)
Feces consists of:
Undigested foodstuffs, inorganic materials, water, and bacteria (75% water) (brown color from breakdown of bile)
Gases from intestinal tract
Methane, hydrogen sulfide, and ammonia; approximately 150ml and absorbed and detox by liver or expelled as flatus
