Observing Emulsification and Comparing the Actions of Saliva and Pepsin: Lab report describing how emulsification may be observed in the lab

Introduction Aim: The objectives of this lab experiment ar to keep up the process of emulsification and to canvas the actions of pepsin and saliva (Amylase). Background Information: The do work of the human digestive corpse is to digest intellectual nourishment that is interpreted in. Digestion is the process by which large, abounding-blooded substances such as fats and proteins argon unkept carry out into underage fat-soluble substances. Digestion consists of two main(prenominal) processes, physical digestion and chemical digestion. physical digestion is the blend ining down of foods by physical means, i.e., not changing the substance itself, only its state. corporeal digestion takes place mainly in the mouth and potbelly, where it is chewed, grinded, and mixed. Chemical digestion breaks down large molecular substances into simpler substances, changing their chemical properties and structure, exploitation digestive enzymes. Chemical digestion occurs mainl y in the stomach and beautiful catgut.          tongue containing amylase acts on amylum to break it down into maltose, in the mouth, start the process by which starch is broken down. After it has been swallowed, the food passes down the oesophagus into the stomach.         The stomach consists of stomachic glands that produce gastric juice, which contains pepsin, an enzyme that dissolves proteins into simpler substances called polypeptides. After spending three or four hours in the stomach, the food travels to the itsy-bitsy intestine.

The small intestine is where digestion is com pleted and its soluble products are absorbed! .         The small intestine receives fluid called impudence from the liver. bitterness consists mainly of bile salts and atomic number 11 henry carbonate. The bile is slowly secreted into the first part of the small intestine, the duodenum. This is where emulsification takes place. Emulsification is a physical process whereby large globules of fat are broken down into smaller globules and made water soluble, using bile salts.         Bile salts are types of...
