Give names of various gastric intestinal hormones and describe their functions.

Explanation

The activities of the gastro intestinal tract are under neural and hormonal control for proper coordination of different parts.
The sight, smell and/or the presence of food in the oral cavity can stimulate the secretion of a saliva.
Gastric and intestinal secretions are also similarly stimulated by neural signals. The muscular activities of different parts of the alimentary canal also be moderated by neural mechanisms both local and through CNS.
Hormonal control of the secretion of digestive juices is carried out by the local hormones produced by the gastric and intestinal mucosa.
