What is the length of the small intestine? 

The length of the small intestine varies, but in adults, it is typically 7.5 metres long. 

The small intestine is an important part of the digestive system as it is responsible for the digestion of food and nutrient absorption. 

It is narrow and tubular in shape, with three segments: the duodenum, jejunum, and ileum. 

The walls of the small intestine are lined with finger-like projections known as villi and microvilli, which increase the surface area available for digestion and absorption. 

The small intestine collaborates with other digestive system organs such as the stomach and pancreas to break down food and extract nutrients needed for the body to function properly.
