What is mechanical digestion?

digestion can be either chemical or mechanical. Mechanical digestion is to break food into smaller particles to make it easier to process the digestive system. The best example is chewing, which is a term for chewing. The teeth chop food into smaller pieces, which then pass through the digestive system. Chemical digestion is the division of food particles by chemical reactions. Chemical and mechanical digestion is combined for food processing, absorbing nutrients and minerals and waste discardation. The act of chewing food breaks it into easier pieces. The stomach performs a little mechanical digestion when the muscles are expanding and downloading to move the food in the stomach. This is for the purpose of exposing meals of more chemical secretions in the stomach, so it is easier. Movement of food in the same way, through muscle contracts also occurs in small and large intestines. There are two groups of muscles that work simultaneously to move food. Circular muscles and longitudinal muscles work in conjunction. The first group of the group, then dRuhá. The earthworm moves a similar number of muscle contractions.

The chemical digestion process begins in the mouth that eliminates saliva, chemicals that try to start spending food as soon as it is consumed. Slivals, also called spitting or drool, come from the salivary glands found in the mouth and are 98% water. There are three main pairs of salivary glands and hundreds of smaller ones.

Chemical digestion that occurs in the stomach is mainly through enzymes and hydrochloric acid. The mystery of the stomach pepsinogen, which turns into Pepsin and decomposes proteins. Hydrochloric acid provides low pH levels in which enzymes can prosper. The combination of enzymes and gastric acids also helps kill any bacteria that can lurk in the diet. The chewed food that enters the stomach is called Bolus and is called Chyme after leaving the stomach.

after the food leaves the stomach, entryIt is to the small intestine, where three more liquids are added to spend more. The liver produces bile and stores it in the gallbladder until it is needed. Spankreas excludes pancreatic juice, which is also used to decompose food. Finally, the food is further clenched by enzymes excreted from the mucous membranes in the small intestine. The food is still moving through peristalsis and leaving the small intestine and entering the large intestine, where many nutrients are absorbed, and the waste then ends the body through the rectum.
