The duodenum is the first part of the small intestine, located just after the stomach. It plays a crucial role in the digestion process by receiving partially digested food from the stomach and further breaking it down with the help of digestive enzymes.
Structure of the Duodenum
The duodenum is C-shaped and is divided into four parts: the superior part, descending part, horizontal part, and ascending part. It is approximately 25-30 cm long and is connected to the stomach via the pyloric sphincter and to the jejunum (the second part of the small intestine) through the duodenojejunal flexure.
Functions of the Duodenum
One of the primary functions of the duodenum is to neutralize the acidic chyme (partially digested food) that enters it from the stomach. It does this by secreting bicarbonate ions to raise the pH level, creating a more alkaline environment for enzymes to work optimally.
Another important function of the duodenum is the absorption of nutrients. While most nutrients are absorbed in the jejunum and ileum, the duodenum plays a role in absorbing certain minerals, vitamins, and iron.
Common Duodenal Disorders
Peptic ulcers are a common disorder that affects the duodenum. They are sores in the lining of the duodenum caused by an imbalance between stomach acid and the protective mechanisms of the stomach and duodenum.
Duodenitis is another common disorder that involves inflammation of the duodenum, often caused by infections, medications, or excessive alcohol consumption. Symptoms may include abdominal pain, bloating, nausea, and vomiting.
In conclusion, the duodenum plays a vital role in the digestive process, helping to break down food and absorb essential nutrients. Understanding its structure and functions can provide insights into various gastrointestinal disorders that may affect this important part of the small intestine.

- A blockage in the duodenums can lead to serious complications and require medical intervention.
- Certain medications can cause irritation to the lining of the duodenums, resulting in gastritis.
- The duodenums secrete digestive enzymes that help break down food for proper absorption.
