Question

Organ where pancreatic enzymes and bile enter the alimentary canal

Answer 1

The duodenum is the organ where pancreatic enzymes and bile enter the alimentary canal. Pancreatic juices and bile contribute to the neutralization of chyme and the digestion of fats, proteins, and carbohydrates. These substances are regulated into the duodenum by the hepatopancreatic sphincter at the ampulla of Vater.

Step-by-step explanation:

The organ where pancreatic enzymes and bile enter the alimentary canal is the duodenum. The duodenum, which is the first part of the small intestine, receives chyme from the stomach separated by the pyloric sphincter. In this 'C-shaped' region of the alimentary canal, the acidic chyme is mixed with alkaline pancreatic juices rich in bicarbonate, which helps to neutralize acidity and supports the digestion process. Not only do pancreatic enzymes break down starches, disaccharides, proteins, and fats, but the bile produced in the liver, stored and concentrated in the gallbladder, and which enters the duodenum through the bile duct, contains bile salts that emulsify lipids, aiding in their digestion.

The intersection where both the bile and pancreatic juices enter the duodenum is known as the hepatopancreatic ampulla (also known as the ampulla of Vater), located in the duodenal wall. The main pancreatic duct and the bile duct converge at this ampulla, which opens into the duodenum at the major duodenal papilla. The flow of these digestive juices into the duodenum is regulated by the hepatopancreatic sphincter (sphincter of Oddi).

Answer 2

Answer: Doedunum

Explanation: Doedunum is a hollow tube that forms part of the digestive tract. It is attached to the pyloric sphincter of the stomach and to the jejunum of the small intestine, that way it plays a huge role in receiving chyme(food) from the stomach and pass it to the small intestine for absorption. Food in the doedunum is taken as signal that initiate enzymatic digestion. Pancreatic juices, bile salts and other enzymes enter the doedunum when it a receives signal that there is food that needs to be digested, broken down by enzymes, then passed on to the jejunum for absorption.
