Detailed explanation-1: -Explanation: The liver is responsible for synthesizing bile salts; these salts are transferred into the gallbladder as bile. The gallbladder stores bile, which it then secretes into the small intestine. Bile contributes to digestion by breaking up large fat globules, a process known as emulsification.
Detailed explanation-2: -Examples of physical digestion, also known as mechanical digestion, are the act of chewing, as well as peristalsis in the stomach.
Detailed explanation-3: -Answer and Explanation: The answer is bile salts. Bile is a mixture of substances produced by the liver, stored in the gallbladder, and delivered to the small intestine.
Detailed explanation-4: -The emulsification of fats is done by bile. Bile breaks down fats into smaller droplets so that they can be easily digested. This does not happen in the mouth and no chewing is involved. Therefore, emulsification is a chemical process aided by the chemical bile.
Detailed explanation-5: -Emulsification in digestion is the breakdown of fat globules in the duodenum into small droplets creating a larger area where the pancreatic lipase enzyme can work to digest the fat into fatty acids and glycerol. The activity of the bile salts helps to emulsify the fats.
