What is "small intestine"?
The small intestine is a long, tube-like organ in the digestive system of the human body. It is responsible for the majority of nutrient absorption from the food we eat. Comprised of three segments, namely the duodenum, jejunum, and ileum, the small intestine plays a vital role in breaking down food into smaller molecules for efficient absorption. It is lined with millions of tiny finger-like projections called villi, which increase its surface area and aid in nutrient absorption. The small intestine also receives secretions from the liver and pancreas, further assisting in digestion and nutrient processing.
Example
The medical team decided to transplant a small intestine, addressing severe digestive issues.
The pancreas functions as both an endocrine and exocrine organ, releasing digestive enzymes into the small intestine through ducts.
