The intrinsic factor is involved in the absorption of vitamin B5

1.     Proton pump inhibitors (PPIs) increase stomach acid

  Which of the following are considered PPIs?

Secreted by  Chief Cells, Pepsinogen can be converted to Pepsin once we get the HCl acid and pepsin digests meat collagen proteins

  Pepsinogen is an active protein

  Pepsin is an active enzyme

Which of the following are part of the gastric motility?

Gastric motility is caused by our parasympathetic and sympathetic nervous system

Parasympathetic stimulation causes inhibition of gastrointestinal secretion and motor activity, and contraction of gastrointestinal sphincters and blood vessels

Parasympathetic stimuli typically stimulate digestive activities such as gastrointestinal secretion and motor activity, and contraction of gastrointestinal sphincters and blood vessels

Increases the frequency of AP’s and force of contraction

Decreases contraction and AP’s

  Meal composition affects the rate of gastric emptying

Ulcers are considered as pathologies because they degrade the epithelium cell lining when acid gets there and destroys it

Stimulated by CCK

Secretes histamine

Secretes acid and intrinsic factor

Secretes a zymogen

Secretes gastrin
