Salivary And Gastric Secretions

Question 1

Helicobacter pylori

Answer 1

Gastric and duodenal ulcers
Bacteria release cytotoxins onto mucosa and damage alkaline mucous layer, increases production of H due to inhibited somatostatin

Question 2

Zollinger-Ellison Syndrome

Answer 2

Rare disorder which pancreatic tumors produce excess quantities of gastrin

Question 3

Salvia

Answer 3

High bicarbonate and K, amylase, and lingual lipase
Parasympathetic and sympathetic increase
Sleep, dehydration, and atropine decrease

Question 4

Gastric secretion

Answer 4

HCl, HIGH K
Pepsinogen, intrinsic factor
Gastrin, Ach, Histamine, PNS increase
H in stomach, chyme in duodenum, somatostatin, atropine, omeprazole decrease

Question 5
