The jejunum and ileum are the two bottom parts of the small intestine. The small intestine is a component of an animal’s alimentary canal that is primarily responsible for nutrition absorption. In addition to absorption, the small intestine also undergoes mechanical and chemical digestion.
There is no natural distinction between the jejunum and the ileum. However, there is a distinction between the jejunum and the ileum.
Jejunum vs Ileum
The main difference between jejunum and ileum is that jejunum absorbs completely digested carbs and proteins, whereas ileum absorbs non-absorbed jejunum particles. The jejunum is the middle portion of the small intestine, on the other hand ileum is at the end. In comparison to the jejunum, the ileum has a greater number of arterial arcades (p 0.0001) and arteriae recta (p = 0.02).
