Stretch receptors located in the duodenum and jejunum initiate a long-lasting reflex that relaxes the internal anal sphincter several hours after food initially passes from the stomach to the intestines.B. Stretch receptors located in the rectal wall initiate the defecation reflex inresponse to an incoming mass movement.C. The defecation reflex involves contraction of the rectal wall and simultaneous relaxation of the internal anal sphincter.D. Digestive fluids secreted from the pancreas and gall bladder contain enzymesthat act on the smooth muscle of the intestine, stimulating peristalsis.E. Conscious signals from the cortex will allow for relaxation of the external anal sphincter (when appropriate!).arrow_forwardWhich of the following statements about gastric secretion of HCl is FALSE? a.

All of the choices.arrow_forwardHow does Jane's problem with Ulcerative Colitis differ from Crohn’s disease (another Inflammatory Bowel Disease)? A. The damage to Jane’s GI tract is localized to the large intestine (colon), whereas patients with Crohn’s disease may have any part of the GI tract affected in the form of “skip” lesions. B. A patient with Crohn’s disease is more likely to have bloody stool than Jane. C. The entire thickness of the Jane’s intestinal wall (mucosa, submucosa, smooth muscle, and serosa) may be affected, whereas only the mucosa is affected in patients with Crohn’s disease. D. Jane may benefit from using a nicotine patch or chewing nicotine gum, while evidence for a therapeutic benefit of nicotine in Crohn’s disease is more limited. E. Anti-inflammatory pharmaceuticals, such as steroids and immunomodulators, are used to treat Crohn’s disease but not Ulcerative Colitis.arrow_forward
