THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Bile salts break down larger fat globules in food into small droplets of fat. Smaller fat droplets are easier for the digestive enzymes from the pancreas to process and break down. The bile salts also help the cells in the bowel to absorb these fat droplets.

Detailed explanation-2: -Lipase is the major enzyme that breaks down dietary fats into smaller molecules called fatty acids and glycerol.

Detailed explanation-3: -Bile grabs onto the fats, and the emulsifiers increase their surface area, making them easier for digestive enzymes to act on. Following this, enzymes break apart fatty acids. Lipase from the pancreas further digests fats into monoglycerides and fatty acids.

Detailed explanation-4: -Each time, small amounts of bile salts escape absorption and reach the large intestine, where they are broken down by bacteria. Some bile salts are reabsorbed in the large intestine. The rest are excreted in the stool.
