Sodium and glucose share a common active transportcarrier (sodium-glucose ligand transporter 1 [SGLT1]).3.What is the cause of gastroesophageal reflux disease?a.Excessive production of hydrochloric acidb.Zone of low pressure of the lower esophageal sphincterc.Presence ofHelicobacter pyloriin the esophagusd.Reverse muscular peristalsis of the esophagusZone of low pressure of the lower esophageal sphincter. Normally, the restingtone of the lower esophageal sphincter maintains a zone of high pressure thatprevents gastroesophageal reflux. In individuals who develop reflux esophagitis,this pressure tends to be lower than normal from either transient relaxation or aweakness of the sphincter.4.By what mechanism does intussusception cause an intestinal obstruction?a.Telescoping of part of the intestine into another section of intestine,usually causing strangulation of the blood supplyb.Twisting the intestine on its mesenteric pedicle, causing occlusion of theblood supplyc.Loss of peristaltic motor activity in the intestine, causing an adynamic ileusPreview Mode
