The duodenum is located in your gastrointestinal tract just past the stomach. Some textbooks describe it as being the first part of the small intestine, while others consider it to be a separate organ entirely. Regardless of this debate, the duodenum is a small tube approximately 10 inches long and not more than an inch or two in diameter.
The duodenum is broken in to four parts. These four parts are somewhat arbitrary, and are used mostly by surgeons to enable them to describe the area they are working around in more detail. The entire duodenum is essentially a long tube. At the bottom of the stomach is a small valve known as the gasteroduodenal junction. Just pass this junction is the first part of the duodenum. The first part of the duodenum is located very close to the liver and pancreas.
Approximately 3 inches past the gasteroduodenal junction, the duodenum begins to curve around the pancreas. It is in this area where there is a drain which leads to the bile duct. Bile is drained from the gallbladder into this portion of the duodenum. This aids in digestion of many different types of foods.
Because of the duodenum's close proximity to the gallbladder, gallstones may have an effect on the duodenum. A gallstone which jams into the bile duct can ulcerate into the duodenum, causing a significant obstruction in your gastrointestinal system. This condition is known as gallstone ileus. It can be very painful and is a serious medical condition which often requires surgery to correct.
Any ulceration through the duodenum, which is a form of peptic ulcer disease, can damage many of the organs around the duodenum. The pancreas is one of the most sensitive organs to an ulceration. It is located quite close to the duodenum. As such, a duodenal ulcer can cause significant damage to the pancreas.
The far end of the duodenum leads to another structure known as the jejunum. The jejunum is either the first part of the small intestine, or the second part if you consider the duodenum to be the first part of the small intestine.
What else can I help you with?
Into what structure does the gallbladder empty?
The duodenum
What structure empties bile into the duodenum?
The common bile duct is the structure that empties bile into the duodenum. It combines bile from the liver and gallbladder and carries it to the duodenum to aid in digestion.
What is A structure that does not manufacture and digestive substance?
duodenum
What is the structure found after the pyloric sphincter?
The duodenum
A structure that produces no digestive secretions of any kind is the?
duodenum
Is the duodenum an accessory structure of the digestive system?
No, the duodenum is actually a primary structure of the digestive system. It is the first part of the small intestine and plays a crucial role in the absorption of nutrients from food.
What structure is located between the common bile duct and the duodenum?
Liver
Structure derived from the foregut portion of the gut tube during development?
pharynx to part 2 of the duodenum
Where does the common bile duct empties?
The common bile duct empties into the duodenum, which is the first part of the small intestine. This connection allows bile produced in the liver and stored in the gallbladder to be released into the digestive system to aid in the digestion and absorption of fats.
Does the pancreatic duct transport secretions from the pancreas to the duodenum?
Pancreatic digestive juices are carried by a tube-like structure known as the pancreatic duct.
What is the excretory systems key structure in order?
mouth, oesophagus, stomach, duodenum, small intestine, large intestine, rectum, anus
What is the name of the first 10 inches of the small intestine?
The first 10 inches of the small intestine is called the duodenum. It is responsible for receiving partially digested food from the stomach and continues the process of digestion by mixing it with digestive enzymes from the pancreas and bile from the liver.
