INTESTINUM JEJUNUM Meaning and
Definition
-
Intestinum jejunum, commonly known as the jejunum, is a section of the small intestine located between the duodenum and the ileum. It is part of the gastrointestinal tract, responsible for the digestion and absorption of nutrients from the food we consume.
The jejunum is approximately 2.5 meters long and is situated in the middle part of the small intestine. It is distinguished by its vascularity, as it contains an extensive network of blood vessels that aid in nutrient absorption. The inner lining of the jejunum is composed of numerous finger-like projections called villi, which further increase the surface area available for absorption.
This portion of the small intestine plays a crucial role in the digestion process. After food leaves the stomach and enters the duodenum, the jejunum continues the breakdown of complex molecules into simpler forms. It absorbs the digested nutrients, such as glucose, amino acids, and fatty acids, along with vitamins, minerals, and water.
The jejunum works in coordination with other segments of the digestive system, including the pancreas and the liver, which secrete digestive enzymes and bile, respectively. The digestive contents pass through the jejunum via a series of muscular contractions, known as peristalsis, which facilitates their movement forward.
In summary, the jejunum is an integral part of the small intestine that is responsible for the absorption of nutrients into the bloodstream. Its specialized structure and functionality make it vital for proper digestion and absorption of essential substances necessary for the body's functioning.

Etymology of INTESTINUM JEJUNUM
The term "intestinum jejunum" comes from Latin, specifically from the words "intestinum" and "jejunum".
1. Intestinum: This word is derived from the Latin term "intestinum (saltus)" which translates to "internal (passage)". It originated from the Latin adjective "intestinus", meaning "internal" or "inner". The term was used to refer to the internal organs or intestines as a whole.
2. Jejunum: The word "jejunum" comes from the Latin term "jejunus", which means "empty" or "fasting". It was used to describe the section of the small intestine that appeared empty upon dissection because it did not contain any food at that time.
