[ˈɪliəm ]
Definition
anatomy physiology
The ileum is the third and final part of the small intestine, following the jejunum and preceding the cecum. It is responsible for the absorption of nutrients and bile salts, and it plays a critical role in the digestive system.
Examples of usage
- The ileum absorbs vitamin B12 and bile acids.
- In cases of Crohn's disease, the ileum may become inflamed.
- Surgeons often take the ileum into account during abdominal operations.

Interesting Facts
Biology
- The ileum measures about 3 to 5 meters long in adults, making it the longest section of the small intestine.
- It plays a crucial role in the absorption of vitamin B12 and bile acids, which are essential for digestion.
- The ileum has specialized structures called Peyer's patches, which are important for immune response in the gut.
Health
- Conditions like Crohn's disease often affect the ileum, leading to symptoms like abdominal pain and nutritional deficiencies.
- Removal of the ileum (ilectomy) can result in short bowel syndrome, affecting a person's ability to absorb nutrients.
- The ileum's health is vital for preventing malnutrition, highlighting the connection between the digestive system and overall well-being.
Cultural References
- In some cultures, digestive health is viewed through the lens of holistic practices, emphasizing the role of the ileum in overall health.
- Certain culinary traditions promote foods that support gut health, understanding that a healthy ileum contributes to better digestion.

Origin of 'ileum'
Main points about word origin
- The term 'ileum' comes from the Latin word 'ile,' meaning 'twisted,' reflecting the curved shape of the intestine.
- It was first described in the writings of ancient anatomists, indicating its long-standing significance in understanding the human body.
- Historically, the ileum's function wasn't fully understood until the development of modern anatomical studies in the 16th century.
The term 'ileum' originates from the Latin word 'ileus', which means 'twisted', as it refers to the twisting structure of the intestines. This part of the intestine was described in medical texts dating back to ancient Greece, with contributions from Hippocrates and Galen paving the way for later anatomical studies. As medical knowledge advanced, the ileum was identified as a distinct section of the small intestine, critical for nutrient absorption. The differentiation of the ileum from other parts of the intestines evolved with the development of surgical techniques and diagnostic tools, solidifying its importance in both anatomy and medical practice.
