Consider the following statement regarding human.a. Duodenum is the lo...
Statement a: Duodenum is the longest part of small intestine.
This statement is incorrect. The duodenum is actually the shortest part of the small intestine. It is the first segment of the small intestine and is responsible for receiving partially digested food, as well as digestive juices from the stomach and pancreas.
Statement b: Hepatic and cystic ducts release their secretions into common bile duct whose opening is controlled by sphincter of Oddi.
This statement is correct. The hepatic duct carries bile from the liver, the cystic duct carries bile from the gallbladder, and both ducts join together to form the common bile duct. The common bile duct then releases its secretions, including bile, into the duodenum. The opening of the common bile duct into the duodenum is controlled by a muscular valve called the sphincter of Oddi.
Statement c: Ileocaecal valve is present at the junction of small intestine and large intestine.
This statement is correct. The ileocaecal valve is a one-way valve located at the junction of the small intestine (specifically the ileum) and the large intestine (specifically the cecum). It prevents the backflow of contents from the large intestine into the small intestine, ensuring that the digested food moves in the correct direction through the digestive system.
Statement d: Mechanical digestion and chemical digestion of food occurs in buccal cavity, stomach and small intestine.
This statement is correct. Mechanical digestion refers to the physical breakdown of food into smaller pieces, and it occurs in the buccal cavity (mouth) through chewing and in the stomach through churning and mixing of food. Chemical digestion refers to the breakdown of food molecules by enzymes, and it occurs in the buccal cavity (through saliva), stomach (through gastric juices), and small intestine (through pancreatic and intestinal enzymes). The small intestine is the primary site of chemical digestion, where most of the nutrients are broken down and absorbed into the bloodstream.
Conclusion: Based on the analysis of each statement, the correct choice is option 'D' - C and D only.
