This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach. The large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This process, called ingestion, has to take place before anything else can happen. The first activity of the digestive system is to take in food through the mouth. The digestive system prepares nutrients for utilization by body cells through six activities, or functions. After the nutrients are absorbed, they are available to all cells in the body and are utilized by the body cells in metabolism. These organs secrete fluids into the digestive tract.įood undergoes three types of processes in the body:ĭigestion and absorption occur in the digestive tract. The salivary glands, liver, gallbladder, and pancreas are major accessory organs that have a role in digestion.
The tongue and teeth are accessory structures located in the mouth. It includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The digestive tract, also called the alimentary canal or gastrointestinal (GI) tract, consists of a long continuous tube that extends from the mouth to the anus. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated. The digestive system includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body. He has training in Basic course workshop in Medical Education Technologies.Acknowledgements Introduction to the Digestive System He has also served as member organising committee of various international & national conferences.

He has supervised MD candidate work on radiological morphometry of distal radioulnar joint. He is member Editorial board of many journal, he has also been invited to review manuscripts in journals of international repute. With his broadened interest in interdisciplinary and biomedical research,Presently he is working on Bioceramics and polymers for implant materials. thats why his area of interest in research is to validate the anatomical aspects in clinical Perspective. Moreover, with his comprehensive knowledge on anatomy, he imparted the applied aspects of the subjects in different field of medicine and also in surgical management of diseases. In classroom teaching, he gives stress on clinical aspects of anatomy to aetiology and diagnosis of the disease.
He takes keen interest in teaching anatomy, explaining anatomical basis of diseases and its presentation.
He joined as lecturer in June 2002 in the Department of Anatomy. Orth & MS (Anatomy) from JNMC, AMU Aligarh.
