Digestive System Digestive system includes the stomach‚ liver‚ pancreas‚ duodenum‚ ileum and colon. What is a Digestive system? Digestion is a breakdown and transportation of the solid and liquid food into microscopic substances therefore theses substances are then transported into different areas of the body The digestive system is a set of organs which transforms whatever we eat into substances that can be used in the body for energy‚ growth and repair. Once the food has been

each of them playing a specific role. These food groups are present in our every day food and are taken into our body through a process of digestion. The food is chewed up and broken down into smaller bits in the mouth and then travels down to the stomach where it is broken down further by the hydrochloric acid in the stomach in a process called chemical digestion. Once the food has been broken down it is then absorbed by the blood to provide the various functions that our body needs to survive. We

FOOD 1. Food is a basic necessity for all living things. 2. Food is important in order to : (a) Provide energy to carry out physical activities. (b) Provide energy for the physiological activities in life such as reproduction‚ digestion and excretion. (c) Build new cells and ti repair tissues in the body. (d) Protect the body from deseases. (e) Maintain the body temperature. (f) Promote growth. 3. Food can be divided into

potatoes‚ dried peas and beans‚ rice‚ pasta‚ fruits‚ and vegetables. Many of these foods contain both starch and fibre. The digestible carbohydrates such as starch and sugar are broken into simpler molecules by enzymes in the saliva‚ in juice produced by the pancreas‚ and in the lining of the small intestine. Starch is digested in two steps. First‚ an enzyme in the saliva and pancreatic juice breaks the starch into molecules called maltose. Then an enzyme in the lining of the small intestine splits the maltose

we begin to salivate‚ we have glands‚ three big glands that are going to produce saliva that is going to empty into our mouth. Now the saliva has water in it but it mostly has mucus and also an enzyme called amylase. And amylase breaks down starch (amylose starch) and so it’s going to break down‚ or start to break down the carbohydrate. So basically are teeth

affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow color‚ but iodine and starch react to produce a
