The alimentary tract of the digestive system is composed of the mouth, pharynx, esophagus, stomach, small and large intestines, rectum and anus. Associated with the alimentary tract are the following accessory organs: salivary glands, liver, gallbladder, and pancreas.

Small intestine is divided three parts, which are duodenum, jejunum and ileum which helps in absorption of nutrients from the digested food, while Large intestine has four parts, which are colon, rectum, caecum and anal canal which helps in absorption of water and electrolytes, as well in production of vitamins like B ...

The digestive system has three main functions. They are digestion, absorption, and elimination. The digestive system starts at the mouth when food gets bitten into smaller and smaller pieces and is mixed with saliva. The teeth crush and grind the food.

The digestive system (cat) (dog) includes the mouth, teeth, salivary glands, esophagus, stomach, intestine, pancreas, liver and gall bladder. The digestive system absorbs and digests food and eliminates solid wastes from the body. The integumentary system is the skin and fur that cover the animal's body.

The bowel is part of the digestive system. It is made up of the small bowel (small intestine) and the large bowel (colon and rectum). The small bowel is longer than the large bowel but it gets its name from the fact it is much narrower than the large bowel. Cancer is more likely to develop in the large bowel.

What is the digestive system? The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.

Human digestive system. The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat as energy, our body has to break the food down into smaller molecules that it can process; it also has to excrete (or get rid of) waste.

The GI tract contains four layers: the innermost layer is the mucosa, underneath this is the submucosa, followed by the muscularis propria and finally, the outermost layer - the adventitia. The structure of these layers varies, in different regions of the digestive system, depending on their function.

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body. The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.

The digestive system includes the organs of the alimentary canal and accessory structures. The alimentary canal forms a continuous tube that is open to the outside environment at both ends. The organs of the alimentary canal are the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.

The digestive system is responsible for taking whole foods and turning them into energy and nutrients to allow the body to function, grow, and repair itself. The six primary processes of the digestive system include: Ingestion of food. Secretion of fluids and digestive enzymes.

Summary. The digestive system consists of organs that break down food, absorb its nutrients, and expel any remaining food waste. Digestion is the process of breaking down food into components that the body can absorb. It includes mechanical digestion and chemical digestion.

The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus. Helping them along the way are the pancreas, gall bladder and liver. Here's how these organs work together in your digestive system.

GI Tract (gastro-intestinal tract or alimentary canal): consist of any part of the digestive system through which the food being processed could pass. This includes, but is not limited to, the esophagus, stomach, and even the cecum (caecum).

The digestive system is the parts of the body that digest food; it is also called the gastrointestinal system. It breaks down food into simple chemicals that can be absorbed into the blood stream. From the blood stream, nutrients go first to the liver, which is a kind of chemical factory for the body.
