Transcript of Digestive System

How does your body digest different types of foods? Digestive System Fats Proteins Carbohydrates Fat Digestion Fat molecules are a rich source of energy for the body. The teeth grind and chew the food breaking it into smaller pieces for easier swallowing and digestion. Fats do not dissolve in water so the digestion of fats is different than other foods. The bile acids produced by the liver and stored in the gallbladder break down the fat globules into tiny droplets. This then allows pancreatic and intestinal enzymes to break the larger molecules into smaller molecules. Some of the smaller molecules are cholesterol. The bile acids combine with these cholesterol molecules, which then combine together and are passed through vessels called lymphatics and are transported to the veins in the chest and blood transports fat to the different parts of the body that store it. Examples: chest, abdomen and buttocks


Protein Digestion Proteins play an important role in building and repairing body tissues.Foods such as beans, meat and eggs contain huge molecules of protein that must be broken down by enzymes. The teeth grind and chew the food and then it travels down the esophagus and an enzyme in the stomach starts digesting the proteins. Enzymes from the pancreas break down the molecules of proteins into amino acids.Amino acids are then absorbed by the blood and carried to all the different parts of the body. Carbohydrates Digestion Enzymes in the saliva, small intestine and pancreas break down starches and sugars into smaller molecules. Starches are broken down in two steps first an enzyme in the salive and the pancreas break them down into maltose and then an enzyme in the small intestine splits the maltose into glucose which then can be absorbed by the blood and transported to the liver for storage. Then carbohydrates are used for sources of energy for the work of the body. Chemical Digestion- Chemical digestion is any digestion in the body in which acid is used to break down food. Physical Digestion- Physical digestion is when you use your teeth to break down food. Extracellular and Intracellular Extracellular- Any digestion that occurs inside the cell.

Intracellular- Any digestion that occurs inside the cell. Enzymes Metabolic enzymes- These are located in your body and their function is to build and repair cells and tissues. They are also a large part of our immune systems. Metabolic enzymes carry out the body's work.

Food Enzymes- These enzymes reside in raw food (not cooked or processed). Food enzymes help with the digestion and assimilation of the food's nutrients.

Digestive Enzymes- These enzymes assist in the breakdown of cooked food. Cooked food has no live enzymes to assist in the breakdown of the dead food so the body must supply the enzymes. Digestive enzymes are limited in the body and if pushed beyond their reserves will borrow from the metabolic enzymes which sets the cycle for degenerative disease. What may have caused James to be sick, according to the symptoms?

Trichinosis, also called trichinellosis, or trichiniasis, is a parasitic disease caused by eating raw or undercooked pork or wild game infected with the larvae of a species of roundworm Trichinella spiralis. Meat must be cooked thoroughly in order to prevent trichinosis. Once you have determined a cause explain what effect this would have on the body.

Trichinosis is a disease caused by parasites, called trichinella that can infect and damage many body tissues. Although the parasites can pass through the intestinal tract and other tissues, muscle tissues are where the majority of them persist. Trichinosis is usually characterized by two phases; the initial phase (intestinal) of abdominal discomfort, diarrhea, and nausea that begins one to two days after ingestion and the second phase (muscle) of muscle aches, itching, fever, chills, and joint pains that begins about two to eight weeks after ingestion. why did Kim tell her brother he was going to be sick after eating the raw pork?

Because she knew that raw pork or raw meat contained parasites that would make him sick.
