Hirschsprung's Disease Anatomy
To better understand congenital megacolon, it helps to understand the anatomy of the gastrointestinal tract.
The intestine absorbs nutrients from food and liquids. The intestine is about 22 feet long in an adult. It includes the large intestine and the small intestine.
The large intestine is also known as the colon. It is the last portion of the intestine. The colon has several parts, including:
- Ascending colon: the first section after the small intestine, located on the right side
- Transverse colon: sits horizontally across the upper abdomen
- Descending colon: located on the left side of the abdomen
- Sigmoid: a short, S-shaped section above the rectum
- Rectum: the lowest internal part of the colon
