The various hormonal secretions in the digestive process include:
Secretin: From duodenum
Chole-Cystokinin: From Gall Bladder
Leptin: From Stomach
These hormones help in the secretion of digestive enzymes and the CCK improves perisatalsis and amylase and lipase secretion from the liver. Leptin from stomach gives filling sensation from the stomach.
Many secretions that assist in digestion, but the most import is INSULIN.

Protein digestion in the stomach results primarily from secretions released by the gastric glands. The enzyme that is secreted is called pepsinogen.

The secretions of the pancreas join with bile from the liver to enter the duodenum. These secretions contain enzymes that aid in the digestion of fats, carbohydrates, and proteins.
Digestion is controlled by the parasympathetic division of the autonomic nervous system.
These secretions help lubricate the bolus for smoother swallowing, provide enzymes to break down food particles for digestion, and maintain the right pH level for optimal enzyme activity. They also enhance the taste of the food and stimulate the process of digestion.
