What is the Surface area of small intestines?

The surface area of the small intestines is approximately 250-300 square meters (2,700-3,200 square feet). This vast surface area is crucial for efficient digestion and absorption of nutrients from the food we consume. The small intestines are lined with millions of tiny finger-like projections called villi, which further increase the surface area available for absorption. This extensive surface area allows for efficient exchange of nutrients, electrolytes, and water between the intestinal lumen and the bloodstream.
