Eighty percent of nutrient absorption occurs in the small intestine. The other 20% occurs in the stomach tissues.
The small intestine, or the duodenum, is where most absorption of nutrients occur.

Most of the absorption of nutrients occurs in the small intestine. The inner surface of the small intestine is lined with finger-like projections called villi, which increase the surface area available for absorption. This is where the majority of nutrients from food are absorbed into the bloodstream.
Filtration of the blood and re-absorption of nutrients primarily occur in the kidneys, specifically in the structures called nephrons. The nephrons filter the blood to remove waste products and then reabsorb essential nutrients, electrolytes, and water back into the bloodstream.
The ileum is long in order to facilitate absorption of nutrients from digested food. Its length provides a large surface area for nutrient absorption to occur efficiently. This is important for the body to extract as many nutrients as possible from the food we consume.
Most absorption of nutrients occurs in the small intestine. And as far as digestion itself, it would be after the food particles are small enough to diffuse through the blood capillaries.
Vitamin B6 deficiency occurs rarely. When it does, it is usually associated with poor absorption of nutrients in the gastrointestinal tract
