where does most absorption occur in small intestine

Swallowing 5) Closure of the nasopharynx
Small intestine The three major classes of nutrients that undergo digestion are proteins, lipids (fats) and carbohydrates:
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
Cerebellar tentorium It covers the top of the cerebellum, and supports the occipital lobes of the brain.
Protein (nutrient) Most proteins are decomposed to single amino acids by digestion in the gastro-intestinal tract.[14]
