villi
The large organ that allows nutrients and water to pass through its walls is the intestines, specifically the small intestine. The walls of the small intestine are lined with tiny, finger-like projections called villi, which increase the surface area for absorption. This structure enables the efficient transfer of nutrients and water from digested food into the bloodstream. The large intestine also absorbs water and some remaining nutrients, but its primary function is to consolidate waste.

The wall of the small intestine secretes disaccharidases, which are enzymes responsible for breaking down disaccharides into monosaccharides. This process enables the absorption of sugars like glucose and fructose into the bloodstream for energy.

Intrinsic factor, a protein produced by the stomach, is required for the absorption of vitamin B12 in the small intestine. In the small intestine, vitamin B12 binds to intrinsic factor, forming a complex that can be absorbed through the intestinal wall.
Surface Area and DiffusionThe small intestine is all about maximizing surface area. The immense amount of folding enables it to be very long meaning more surface area. The villi further increases surface area. They are projections that provide even more membrane surface area that food, while passing through the small intestine, will come in contact with. This contact with the membrane of the small intestine is how absorption occurs. Nutrients that are used in the body will diffuse across the intestinal membrane into the blood stream because the concentration will be high inside the intestine and low in the blood plasma. This difference in concentration is what "drives" diffusion across the membrane.
