Nervous Phase: A pouch of Pavlov is prepared in a dog and upon the same animal oesophagus is divided, as done in the experiment of sham feeding. The food, swallowed by the animal, comes out through the cut end of [...]
In this article we will discuss about:- 1. Mechanism of Gastric Secretion 2. Hormones of Gastric Secretion 3. Effects of Various Chemicals and Drugs 4. Investigation. Mechanism of Gastric Secretion: The mechanism of gastric secretion has been chiefly studied on animals. Some direct evidence has been obtained in man, from cases of accidental gastric fistula through which gastric juice could [...]
