Alimentary System function

There are two digestive system parts. It consists of the digestive tract (also known as the alimentary tract or gastrointestinal tract) and some accessory organs that help in the whole digestion process. The alimentary tract length varies in humans, and it is about eight to ten meters (26 feet 2 inches to 32 feet 9 inches) long The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure which starts from the mouth and ends in the anus. The alimentary canal plays a primary role in the human digestion and is also termed as the digestive tract

The alimentary canal is a major part of the digestive system. It is a continuous muscular tube which runs through the body and it is around 8 to 10 meters long. It is open at 2 ends, with the mouth at the anterior end and anus at the posterior end. The alimentary canal performs the function of digesting food The main function of the organs of the alimentary canal is to nourish the body. This tube begins at the mouth and terminates at the anus. Between those two points, the canal is modified as the pharynx, esophagus, stomach, and small and large intestines to fit the functional needs of the body

digestive juices and digestion products. Its functions are (a) Lubricate and facilitate food movement (b) Envelops the food and protects the midgut epithelial cells against harder food particles.

The function of the digestive system is to break down the foods you eat, release their nutrients, and absorb those nutrients into the body. Although the small intestine is the workhorse of the system, where the majority of digestion occurs, and where most of the released nutrients are absorbed into the blood or lymph, each of the digestive system organs makes a vital contribution to this process Structure and Function. The most important point to keep in mind when examining the alimentary system is that normal mucosal and serosal surfaces should be smooth and shiny (although there may be normal papilla, folds, and ridges). The exception to this rule is the rumen, whose papillae may normally have a roughened, dull, surface appearance system [sis´tem] 1. a set or series of interconnected or interdependent parts or entities (objects, organs, or organisms) that act together in a common purpose or produce results impossible by action of one alone. 2. an organized set of principles or ideas. adj., adj systemat´ic, system´ic.
