What differentiates the consequences of secretion of gastrin and cholecystokinin (CCK)?

Summary Introduction

To review:

The differences between the consequences of secretion of gastrin and cholecystokinin.

Introduction:

Animals need energy to perform various functions. They obtain this energy through respiration of biomolecules in the cells. These molecules reach the cells via circulatory systems after digestion, in the digestive system. The digestion process is a highly controlled and regulated process. The passage of food in the digestive tract is controlled by receptors and hormones, released from the digestive tract.

Explanation

The differences between the consequences of secretion of gastrin and cholecystokinin:

Gastrin Cholecystokinin
Gastrin is secreted by the G-cells of stomach. Cholecystokinin is secreted by the I-cells of small intestine.
The proteins in bolus stimulate the secretion of gastrin. The fat and a little protein stimulate the secretion of cholecystokinin.
It travels through the circulatory system and returns to the stomach...
