The Digestive System Example

The Digestive System Example The Digestive System – Coursework Example number The digestive system Different types of foods come along with different nutrients such as vitamins, carbohydrates, fats, minerals, and proteins. These nutrients are often a source of energy and material to the body cells. The problem is that most of these nutrients cannot be used by the body for energy in the form in which they are eaten. Hence, before these nutrients are absorbed and carried to the body cells, they need to be broken out and changed into smaller, usable pieces. This is the work of the digestive system with the help of the digestive organs. The digestive process is a rigorous task carried out by the digestive organs working together in the digestive system (Hoffman, 53). Of concern is whether it is possible to live without one or more of the digestive organs. Each and every digestive organ has its own distinctive role. For this reason, it is impossible to live without one or more digestive organisms. However, the small intestine does the most work of any diges tive organ. This is the point where food is broken down by physical grinding as well as special proteins known as enzymes that work on food at the molecular level. In addition, the small intestine is where almost all of the useful nutrients are absorbed into the body. By this time, all that is left for the large intestines is waste in the form of undigested food. Other digestive organs such as the pancreas, liver, and gallbladder are not part of the twisted tube through which food travels but play important roles in the digestive system (Scott & Fong, 16). Regardless of how minor a role a digestive organ contributes to the digestive system, failure to have one of the digestive organizations can lead to digestive breakdown. Therefore, every digestive organ plays a detrimental role in digestion, and however minor it may appear, its pathology may lead to incomplete digestion.Works cited Hoffman, G. Digestive System.
