What Is the Digestive System? Inflammatory Bowel Disease. The digestive system is the group of organs that break down food in order to absorb nutrients. The nutrients in food are used by the body as fuel to keep all the body systems working. The leftover parts of food which cannot be broken down, digested, or absorbed are excreted as bowel movements.

- Science Main Index. The digestive system is under control of the Autonomic Nervous System (ANS). The ANS controls body process that are not under our conscious control. This means that when we eat food, we don't need to think about how our body will digest it. The Autonomic Nervous System automatically does what needs to be done. The digestive system is also controlled by hormones released by glands in the body.

- The digestive system consists of the digestive tract and accessory digestive organs. The digestive tract is also called the alimentary (relating to nourishment) tract or the gastrointestinal (GI) tract, although the term gastrointestinal technically refers to only the stomach and the intestines.

Digestive System The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).ccessory organs of the digestive system include the teeth, tongue, salivary glands, liver, gallbladder, and pancreas. To achieve the goal of providing energy and nutrients to the body, six major functions take place in the digestive system: 1  Ingestion. 2  Secretion.

- Anatomy of the Digestive System: Digestion is the process in which food is broken into smaller pieces so the body can use them to build and nourish cells and provide energy. The digestive system is comprised of the mouth and salivary glands, esophagus, stomach, small intestine, and large intestine.

Human digestive system Human digestive system. The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder).[1] In this system, the process of digestion has many stages, the first of which starts in the mouth.

The Digestive System The digestive system is a tube through which food passes from the mouth where food is ingested to the anus where it is egested. It consists of a series of organs, each with a distinct structure and function. During the digestive transit food is broken down into substances suitable for absorption into the bloodstream.

Organs include the mouth, pharynx, esophagus, stomach, small and large intestines, liver, gallbladder, and anus. Also called the digestive system.

The Digestive System The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus (see figure). Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. Food follows the path: mouth, esophagus, stomach, small intestine, large intestine, rectum, anus.

intestine The part of the digestive tract that extends from the stomach to the anus, consisting of the small intestine and large intestine. The intestine is a muscular tube in which most of the processes of digestion take place.

- The digestive system is a collection of organs or cells in an organism's body that breaks down food into smaller nutrients the body can use. Our digestive system has an opening and an exit, meaning it is a complete digestive system.

Stomach The stomach is a muscular, hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates. The stomach has a dilated structure and functions as a vital digestive organ. In the digestive system the stomach is involved in the second phase of digestion, following mastication. In humans and many other animals, the stomach is located between the oesophagus and the small intestine. It secretes digestive enzymes and gastric acid to aid in food digestion. Th

Digestive System Digestive System. The human digestive system is responsible for food ingestion and digestion as well as the absorption of digested food molecules and the elimination of undigested molecules. It consists of a long tube called the gastrointestinal tract or GI tract (alimentary canal) and several accessory organs.

- The digestive tract is a series of hollow organs connected by tubes from the mouth to the anus, including the mouth, esophagus, stomach, small intestine, large intestine, colon and rectum. Each of these organs' walls contain layers of muscle that enable them to propel food and liquid through the system.
