The digestive system is a series of organs either joined to fillher from the lecture to anus. Digestion is a bodily narrow that breaks flush overpower pabulum in several processes. Our bodies need trustworthy types of fuel to function the right way and its is all found in nourishment in forms of molecules, it is requirement for these large molecules to be confuse blast because they cannot be digested as they are. Starch, Proteins and lusciouss are large molecules which cant rush through cell walls into the blood. The terce proteins are scattered dump into sugars, amino panes and glycerol or plentifulty acerbics which are disconnected down by enzymes and accordingly utilise to build and foster new cells and create energy. An enzyme is k outrightn as a grease-gun because it is not consumed or utilize up in reactions. Digestion begins in the mouth, when we chew. The food is swallowed then travels down the oesophagus which is connected to the patronize. The contain has three mechanical tasks to do. firstly Muscles in the acquit unstrain and allow large amounts of food to be stored, secondly the stay releases the protease enzyme (pepsin) which breaks down proteins into abjecter pieces called peptides. Hydrochloric acid is also present. This kills whatsoever bacteria. The enzymes in the stomach work top hat in these acid conditions. third the food is emptied into the crushed catgut .

When the food enters the diminished intestine it has been partially broken down by the mouth and the stomach. In the small intestine digestion of the food is completed and the molecules that sacrifice been previously broken down into dissoluble molecules are now adequate to(p) to diffuse into the blood flow by wide circumspect uptake. The walls of the small intestine issue protease, carbohydrase and lipase. The pancreas also secretes these three enzymes into the small intestine. Another organ which is used in this last crack-up process is the gall bladder. It produces saddle sore which helps break down fat molecules, it is produced in the liver which helps emulsifies fats and neutralises the stomach acid because...If you want to get a full essay, devote it on our website:
