The name of the body system i am studying is the Digestive system. It processes the food that goes into your body, grabs the nutrients, and eventually expels the waste in the form of feces. The digestive system has two major sections, the upper and lower gastrointestinal tracts. The upper gastrointestinal tract consists of the mouth, esophagus, pharynx, and stomach, while the lower gastrointestinal tract comprises of the small intestine, large intestine, and the anus. Organs such as the liver, gallbladder, and pancreas also consist of the digestive system

DigestionDigestion is the mechanical and chemical breakdown of food into smaller components that are more easily absorbed into a blood stream, for instance. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. In mammals, food enters the mouth, being chewed by teeth, with chemical processing beginning in chemicals in the saliva from salivary glands. This is called mastication. Then it travels down the esophagus into the stomach, where hydrochloricacid kills most contaminating microorganisms and begins breakdown of some food, andchemical alteration of some. The hydrochloric acid has a low pH, which allows enzymes to work more efficiently. After some time, the resulting thick liquid is called chyme. Chyme will go through the small intestine, where ninety-five percent of absorption of nutrients occurs, then the waste material travels through the large intestine and eventually being eliminated by defacation. Your digestive system is located from your head to your toes, but mostly located in the lower half of your body. If you didn't have your digestive system you would die because, one your body would fill up with an overwhelming amount of waste and pollute your body. Secondly, you wouldn't be getting any nutrients so you would not be able to move or do anything after a few days and eventually die.
