Anatomy of Digestive System: 02 Presented By: Kunwar Navdeep Singh
Salivary glands: Mouth Tongue Parotid gland Sublingual gland Submandibular gland Pharynx Esophagus Liver Stomach Spleen Gallbladder Small intestine: Pancreas Duodenum Jejunum lleum rge intestine: Transverse colon Ascending colon Descending colon Cecum Sigmoid colon Appendix Rectum Anal canal Anus
Cardial notch Esophagus Fundus Cardia Angular incisure Pylorus Body Pyloric canal Duodenum Pyloric antrium
Stomach: The stomach is a muscular organ in the gastrointestinal tract located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. . In the digestive system the stomach is involved in the second phase of digestion, following mastication (chewing).
Structure: Human stomach is divided into four sections, beginning at the cardia, each of which has different cells and functions. The cardia is where the contents of the oesophagus empty into the stomach. . The fundus is formed in the upper curved part. . The body is the main, central region of the stomach The pylorus is the lower section of the stomach that empties contents into the duodenum .
Large Intestine (Colon) Stomach Duodenum Small Intestine Jejunam lleum Rectum Anus Sigmoid Colon
Duodenum: The duodenum is a short structure ranging from 20 cm (7.9 inches) to 25 cm (9.8 inches) in length, and shaped like a "C". It surrounds the head of the pancreas. It receives gastric chyme from the stomach, together with digestive juices from the pancreas (digestive enzymes) and the liver (bile). The duodenum contains Brunner's glands, which produce a mucus-rich alkaline secretion containing bicarbonate. These secretions, in combination with bicarbonate from the pancreas, neutralize the stomach acids contained in gastric chyme. .
lleum: lleum is the final section of the small intestine. It is about 3 m long, and contains villi similar to the jejunum. . It absorbs mainly vitamin B12 and bile acids, as well as any other remaining nutrients. . The ileum joins to the cecum of the large intestine at the ileocecal junction.
Large Intestine: The large intestine, also known as the large bowel, is the last part of the gastrointestinal tract and of the digestive system. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation. The colon is the largest portion of the large intestine.
Colon: The colon is the largest portion of the large intestine & last part of Digestive system The length of the adult human male colon is 65 inches or 166 cm (range of 80 to 313 cm), on average, for females it is 155 cm (range of 80 to 214 cm) . Unlike the small intestine, the colon does not play a major role in absorption of foods and nutrients. .
Colon: . Sections of the colon are: The ascending colon including the cecum and appendix. The transverse colon including the colic flexures and transverse mesocolon. . . The descending colon. The sigmoid colon - the s-shaped region of the large intestine The rectum
