Answer #1

The exocrine and endocrine cells are responsible for the production of certain substance in the stomach. It us controlled by autonomic nervous system and digestive hormones.

Gastric juice is secreted by glands lining the stomach walls.It also produces rennin and pepsin responsible for digestion

HCl is activates pepsinogen secreted by the gastrin

An important enzyme is the pepsin.

The 3 receptor of the parietal cells are

  • H2 receptor stimated by the histamine
  • M3 receptor stimulated by the acetylcholine
  • Gastric receptor stimulated by gastrin
