The food has to be made usable by the consumer by a process of digestion. Material that is indigestible will have to be voided. Foods are usually dead or alive body parts and generally consist of large‚ complex organic molecules that need breaking down to smaller chemically simpler forms. small‚ simple organic and

reintroduces digestive enzymes to the process. Once digestion is completed the nutrients are passed through the intestinal wall and into the bloodstream. For most of us the food entering our stomach is severely enzyme deficient because of processing and cooking. Any food that sustains heat of approximately 118 to 129 degrees fahrenheit destroys the enzymes. The food then sits there for an hour‚ like a heavy lump‚ with very little pre-digestion taking place. This forces the body to produce large

The optic chiasm‚ which is crucial to the visual system‚ was discovered around 100 C.E. by Marinus. Circa 1000‚ Al-Zahrawi‚ living in Spain‚ began to write about different surgical treatments for neurological disorders.

I mostly knew the basics‚ like that food moves from the mouth to the throat to the stomach and then leaves the body. But in reality there is much more to digestion that I didn’t know about. I found plenty of useful information from a lot of different websites. During my research i learned that the epiglottis is a big part of digestion. The epiglottis is cartilage that sits right behind our tongue. The epiglottis lets us swallow the food that we have chewed up. I also learned the gastrointestinal

combination of organs which have been arranged together to help carry out its particular function of turning food into the energy which is necessary to survive and packaging the excess residue for waste disposal. Digestion involves the breakdown of food into smaller components. The process of digestion has many stages with the first starting in the oral cavity. Within the system‚ food passes through a tube called the alimentary canal‚ more commonly known as the gastrointestinal tract. The tract is made up

Parts of the digestive system The digestive system consists primarily of the alimentary canal‚ a tube that extends from the mouth to the rectum. As food moves through this canal‚ it is ground and mixed with various digestive juices. Most of these juices contain digestive enzymes‚ chemicals that speed up reactions involved in the breakdown of food. The stomach and the small intestines‚ which are parts of the alimentary canal‚ each produce a digestive juice. Other digestive juices empty into the alimentary

The proteins would be flushed out of the body quicker than usual with the high vulnerability of malabsorption.
