Students should be able to identify the position of these organs on a diagram of the digestive system. Muscular tube which moves ingested food to the stomach. Gall bladder Stores bile before releasing it into the first section of the small intestine. The muscles in the oesophagus contract above the bolus to push food down the oesophagus. As the food is swallowed it passes over the epiglottis which covers the opening of the respiratory system and prevents food entering it. The digestive system also known as the gut is essentially a long tube about 9 metres long. But not all teeth are the same and are shaped and designed for different jobs. How the Digestive Enzymes Work. Outcome 2. Bile travels down the bile duct into the small intestine, where it neutralises stomach acid.

    Nothing, enzymes will work at any temperature. These enzymes are secreted from here into the small intestine. Bile After it has been in the stomach, food travels to the small intestine.

    Absorption is the movement of digested food molecules through the wall of the intestine into the blood. It works in both acidic and slightly alkaline conditions, and is found in the stomach and small intestine which is slightly alkaline.

    The good blood supply around the villi quickly takes away absorbed nutrients, this maintains a steep concentration gradient so that more diffusion of digested nutrients from the small intestine into the blood can occur.

    Enzymes are biological catalysts. The purpose of digestion is to break down large, insoluble molecules carbohydrates, proteins and lipids into small, soluble molecules that can be absorbed into the bloodstream Food is partially digested mechanically by chewing, churning and emulsification in order to break large pieces of food into smaller pieces of food which increases the surface area for enzymes to work on Digestion mainly takes place chemicallywhere bonds holding the large molecules together are broken to make smaller and smaller molecules Chemical digestion is controlled by enzymes which are produced in different areas of the digestive system There are three main types of digestive enzymes — carbohydrases, proteases and lipases.

    Amylase is used in the mouth and stomach, as it breaks starch into sugars and works best in acidic conditions.

    Enzymes are used to convert food into soluble substances that can be absorbed into the bloodstream.

    After it has been in the stomach, food travels to the small intestine. The villi have very thin walls and a good blood supply which means that the digested food can be easily absorbed from the gut into the blood.

    1. It kills many harmful micro-organisms that might have been swallowed along with the food. Bile is produced in the liver, which is stored in the gall bladder before travelling to the small intestine and neutralising the stomach acid.

    2. The pancreas, a pistol shaped organ, produces the enzymes amylase, lipase and protease and releases them into the small intestine when needed.
