Examinations revealed that he is at the third centile for weight and has a distended abdomen with no palpable organs. His abdominal X-ray showed a narrowed distal colon with proximal dilation. OBJECTIVES: OBJECTIVES Anatomy, embryology and histology of the intestines. Digestion and absorption in the intestines. GIT motility and its neural control. Why the chronic constipation? The possible solutions available for Kofi Manu. ANATOMY OF THE INTESTINES: ANATOMY OF THE INTESTINES Small intestines Large intestines EMBRYOLOGY: EMBRYOLOGY HISTOLOGY: HISTOLOGY Small intestines Large intestines DIGESTION AND ABSORPTION IN THE INTESTINES: DIGESTION AND ABSORPTION IN THE INTESTINES Small intestine: Digestion Absorption Large intestines: Absorption GIT MOTILITY AND NEURAL CONTROL: GIT MOTILITY AND NEURAL CONTROL Regulation of motility of the colon Gastrocolic reflex Defecation reflex GIS is controlled by : autonomic NS, enteric NS Slide 11: Why the chronic constipation? Aganglionosis of the distal colon prevented normal GIT peristalsis. POSSIBLE REMEDY: POSSIBLE REMEDY Surgery: Proctocolectomy CONCLUSION: CONCLUSION References: References Bodian , M.; Carter, C.
