In human alimentary canal, name the site of complete digestion of various components of food. Explain the process of digestion.

Explanation

Small intestine.
Secretions of liver and pancreas mixes with food.Pancreatic enzymes make it alkaline. Bile juice from liver too helps in it. Bile salts break the fat present in the form of large globules into smaller ones, increasing the efficiency of enzyme action. Enzymes like trypsin digests proteins and lipase breaks down fats. Intestinal juice convert proteins to amino acids, complex carbohydrate to glucose and fat into fatty acids and glycerol.
