ANATOMY

Detailed explanation-1: -The digestion of fats begins in the first section of the small intestine, the duodenum. Globules of fat in the acidic chyme coming from the stomach are broken up by intestinal movements, and the smaller droplets become coated with bile molecules that are delivered to the duodenum through the common bile duct.

Detailed explanation-2: -The body begins breaking down fat in the mouth, using enzymes in saliva . Chewing increases the surface area of foods, allowing the enzymes to break down food more effectively. The most important chemicals that help with fat digestion in the mouth are lingual lipase and phospholipids, which turn fats into small drops.

Detailed explanation-3: -Fats are digested into fatty acids and glycerol by an enzyme called lipase . Bile juice is secreted by the liver which helps in the emulsification of fat. Emulsification is a process that breaks down large fat globules into smaller globules so that the pancreatic enzymes can easily act on these smaller fats.

Detailed explanation-4: -Answer and Explanation: When fat enters the duodenum, the release of ‘cholecystokinin’ is signaled which causes the gallbladder to release ‘bile’. The meaning of ‘cholecysto’ is gallbladder and of ‘kinin’ is movement. Cholecystokinin is released due to the presence of fat in the duodenum.
