ANATOMY AND PHYSIOLOGY OF THE DIGESTIVE SYSTEM The digestive system is basically a tube running through the body from the mouth to the anus. The organs of the digestive system include the oral cavity (mouth)‚ esophagus‚ stomach‚ small and large intestine and rectum. Their role is to break down food and deliver the products to the blood for dispersal to the body cells. The undigested food that remains in the tract leaves the body through the anus as feces. The break down activities that

Introduction The Digestive system breaks down the ingested food into absorbable forms of nutrients and absorbs nutrients‚ ions and water from the external environment of the body. It is designed to maximize digestion and absorption. The functional structures of the digestive system are the passage‚ the glands like salivary glands‚ gastric glands‚ pancreatic‚ intestinal glands and liver. Also‚ the four layers of the digestive system are mucosa‚ submucosa‚ muscularis and serosa. The digestive system is regulated

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

There are 206 bones in the human body of the adult skeleton. The adult skeleton is broken up in two divisions: the axial skeleton‚ and the appendicular skeleton. The axil skeleton is made up of 80 bones‚ and the appendicular skeleton is made up of 126 bones. As for the different systems of the body‚ we dissected a fetal

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

The Digestive System Structure and Functions Jermaine Kendrick Vista College 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). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE
