...and what structural features make this organ particularly well-suited for absorption of nutrients into the blood?

Yeah,it's in the small intestine and most precisely in the illeum. And for the structure, the small intestine has many finger-like villi, which provide a large surface for maximum absorption to take place. It is also one cell thick and contains many blood capillaries to transport the absorbed food away.

almost the whole gastrointestinal tract is involved in absorption,some amount of cooked starch and some lipid soluble drugs gets absorbed in the mouth itself then alcohol and some amount of carbohydrates and some minerals r absorbed in the stomach and proteins and lipids r mainly absorbed in the small intestine and finally water along with some minerals gets absorbed in the large intestine.stomach contains gastric mucosa ,small intestine and large intestine contains villi (richly supplied by blood vessels)for absorption

The small intestine has a lining with many tiny, finger-like projections called villi. The villi increase the surface area of the intestinal lining so more nutrients can be absorbed. Each villus has capillaries inside it for absorption.
