Faster digestion also helps the liver and the body to stay clean and nutrients are more readily absorbed. Combination of food offers information on how to create faster digestion that facilitates weight loss.

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE

Bacteria are found in humans from birth‚ where they feed and continue to develop. In the digestive tract they feed from decaying food matter‚ which results in digestion‚ and providing nutrients to the host. Other bacteria host on inanimate objects and decompose things that if left for a while could be unhealthy for a particular environment. The two important chemical processes that are involved in a bacteria cell

food and help your body absorb the nutrients from this food. The digestive system is made up of the digestive tract‚ which includes the esophagus‚ stomach and intestines and other organs that aid in digestion such as the liver‚ pancreas and gall bladder. The breaking down of food for digestion begins in your mouth. As you eat something‚ your teeth break down the food‚ and your saliva helps to breakdown and it moistens the food so you can swallow it easily. Saliva also turns sugars into starch

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse

bolus (lumps of food) squeezes past the epiglottis then down the oesophagus which connects the throat to the stomach. The bolus then enters the stomach where gastric juices are produced by the walls of the stomach. The protease‚ pepsin‚ starts the digestion of proteins to smaller molecules called polypeptides. Hydrochloric acids break the food down further and kills all the bacteria. The stomach then churns everything together (food‚ gastric juices and hydrochloric acid) into a squishy mush; this process

Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical

To answer the first question‚ the Hydrochloric Acid in our stomachs has a very important role for our digestion. It alters the natural qualities of the proteins in our food which makes them vulnerable when they’re attacked by an enzyme named pepsin. (Pepsin from the Latin word pepti which means digested) It also kills the bacteria that can be found in your
