Extracts from this document...

Introduction

P6- Explain how these dietary nutrients are processed through the digestive system M4- Use chemical equations to show how the main food groups are dealt with in the digestive system Dietary nutrients in the digestive system Protein Proteins can be found in many different types of foods. They can be found in beans, meat and even eggs. The proteins contained within this food are used to build and repair body tissues. However, before these body tissues can be repaired by using the proteins, the proteins must be broken down and digested by enzymes in the digestive system. An enzyme breaks down and is in the juice of the stomach. This starts the digestion of the proteins that are contained within different food?s such as meat. Enzymes that are present in the pancreas and the lining of the intestine complete the breakdown of the large protein molecules into the smaller protein molecules. ...read more.

The glucose that is converted from the carbohydrates is then carried out in the bloodstream in the liver and is stored in the body as energy which is provided for the body. Carbohydrates help by providing energy to the body. Examples of carbohydrates are sugars, cellulose and starch. These are broken down into three different types of polysaccharides, monosaccharide and disaccharides. C6 H12 O6 + 6 O2 Fibre Like proteins and carbohydrates fibres are also broken down in the body. Fibres however, are not broken down by enzymes and can be present in food as soluble o insoluble fibres. Soluble fibres dissolve very easily in water and are like a soft gel like texture in the intestines. Soluble fibres reduce the speed of digestion and release energy such as carbohydrates; they also assist in keeping blood pressure low within the body. The insoluble fibres pass unchanged through the intestines. ...read more.

Conclusion

The fat is then carried to the different parts of the body. Triglyceride Water and Salt Water that is given into the body is a substance that goes through the body into the small intestine, where the salt is dissolved. Water and salt comes through food and liquid that is digested into the body. Vitamins Vitamins are also present in many different types of food. These are absorbed through to the small intestine. There are two types of vitamins these are classified as water- soluble and fat- soluble vitamins. Water soluble vitamins are not easily stored in the body and the excess amounts leave the body as excess urine and waste. However fat- soluble vitamins are stored in fats, liver and tissues of the body. There are many vitamins that can be absorbed by the body; Vitamin B and Vitamin C are vitamins that are soluble. Vitamins A, E, K and D are known as fat soluble vitamins, these fat soluble vitamins are stored in the liver and many other fat tissues within the body. Vitamins that are not dissolved easily are removed as excess through the urine. ...read more.
