TRUE OR FALSE: Patients with gastroesophageal reflux disease (GERD) are advised to lie on the left side so that the stomach contents would not go up into the esophagus.
True
Left side: where the stomach is
A hormone from the stomach that causes relaxation of muscle tone
Gastrin
Circular muscle of lower end of ileum serves as a sphincter into colon. Composed of horizontal folds of mucous membrane that projects around the orifice of the ileum.
Ileocecal valve
The defense mechanism against bacteria of typhoid/enteric fever that can only be found on the lowest ileum
Peyer’s patches
What controls the closure of the Gastroesophageal Sphincter?
Vagus nerve and gastrin hormone
What causes a reduced response of the Gastroesophageal Sphincter?
Secretin, cholecystokinin, and glucagon
Paste-like material that will be transported out of the stomach via pylorus to the small intestine for digestion and absorption
