Summary Introduction
To determine:
The action of cholecystokinin (CCK) hormone.
Introduction:
The digestion of food is a complex process. Various enzymes play a vital role in food digestion. The secretion of enzymes is also governed by various factors. Several enzyme secretions are maintained by hormones. Every hormone has a specific site or gland for its action.
