NUR230 Lecture Notes - Lecture 22: Esophagus, Urea Breath Test, Esophageal Motility Disorder
Document Summary
The proton pump of parietal cells regulates synthesis of acid: gastric goblet cells: secrete mucus and prostaglandin e2 (pge2), a lipid-rich molecule, which exerts a strong protective effect. A, d, e, and k are absorbed in the jejunum: the ileum is the last and longest segment of the small intestine. The primary functions of the ileum are the reabsorption of vitamin b12 and the return of bile acids to the liver: the return of bile acids to the liver from the ileum, is termed the enterohepatic circulation process. The uvula and soft palate should rise as the patient vocalizes. If bright red blood is apparent, there is current bleeding occurring from a blood vessel. This is a medical emergency: diagnosis of ugib, cbc, endoscopy, a positive fecal occult blood test (fobt) occurs when there is blood in the stool. If nerve involvement: hiccups, hoarse voice, pain at the back of the throat, chronic cough, odynophagia (painful swallowing).
