What is the role of the duodenum?

Answer 1

The function of the Duodenum is to use the body's chemicals to break down food.

Another way of putting it--

The function of Duodenum, so named because it equates to the length of about 12 fingers, completes digestion of carbohydrates, proteins, and lipids. It also absorbs about 90% of the nutrients and water that pass through the digestive system.

FYI; The Duodenum is the shortest region out all the regions ( Jejunum and Ileum )

Answer 2

It is part of the small intestine and is responsible to distribute bile, pancreatic acids, and other secretions from other glands as a collection of acids and aid in the distribution of these acids into the digesting food matter. This is a further breakdown of fats and other nutrients in nourishing the body. The duodenum releases chyle or chyme that commences the acid soup mix.

Answer 3

The duodenum is responsible for further processing the material from the stomach (called chyme), by secreting enzymes which aid in digestion. Bile and pancreatic juice also enter the duodenum around its midpoint, and by moving the chyme in a shaking kind of motion, the duodenum mixes the chyme with these enzymes within its lumen, further aiding digestion.
Digestion of fats, proteins and carbohydrates contained in the foods you consume, is completed within the small intestine. The resulting nutrients produced are absorbed through the lining of the small intestine and transferred to the bloodstream.

1. Duodenum = Located at the junction of the stomach and the small intestine, the duodenum is the first part of the small intestine. It is C-shaped and about 25 cm long.

• The duodenum receives the thick liquid mixture of partly-digested food and acid from the stomach. This acid is quickly neutralised in the alkaline environment of the duodenum.

• The duodenum also receives bile from the gallbladder, and other digestive enzymes from the pancreas. These enter the duodenum through small ducts or tubes.

• Other glands produce mucus that coats the digestive mixture to help ease its passage.

• The food mixes with bile, mucus, and pancreatic and other digestive enzymes.

• The bulk of the digestion of proteins, fats and carbohydrates takes place in the duodenum before the material travels further into the small intestine.

2. Jejunum and Ileum = The jejunum is the 1-2 m long, coiled mid-section of the small intestine. The ileum is the final portion of the small intestine, which leads into the large intestine. The ileum measures 2-4 m in length.

• The inner linings of the jejunum and ileum contain very small finger-like bumps called 'villi'. The presence of these tiny bumps on the inside of the small intestine means that the surface area is much larger than if the lining were just a flat surface. This increased surface area improves the small intestine's ability to absorb nutrients.

• The final stages of digestion are completed in this portion of the small intestine, where foods and liquids are fully broken down into their nutrient components such as:

 smaller molecules (eg, glucose from carbohydrates; amino acids from proteins; fatty acids and cholesterol from fats)

 vitamins

 minerals

 salts

 water

As the digestive mixture travels through the small intestine, the villi absorb the nutrients and transfer them to the bloodstream and the liver. Any food that has not been digested in the small intestine like fiber (along with some water and vitamins) then reaches the large intestine.
The duodenum is a hollow internal organ that breaks down stuff that goes through the digestive system. It is the first part of the small intestine.

Answer 4

The duodenum is a 10 inch,c shaped segment which curves around the pancreas and connects with the jejunum, and is one of three parts of the small intestines.

The mucosa of the duodenum produces mucus to protect itself from stomach acids

Answer 5

The duodenum's function in the digestive process is to neutralize stomach acids, release proteases to break down proteins, lipases to break down fats, and carbohydrases (also in saliva) to break down the carbohydrates.

Answer 6

It distributes bile and pancreatic acids to help break down food

Answer 7

That is the connection between your stomach and your small intestine.

Answer 8

The main function is to recieve the partially digested foods from the stomach and complete the process of digestion.

Answer 9

The food goes no where.
