After amino acids and monosaccharides are absorbed by the intestinal villi, they are released into the bloodstream. This process occurs through a specialized mechanism in the small intestine, where nutrients are transported across the intestinal epithelium into the capillaries found in the villi.

Once in the bloodstream, these nutrients are then carried away from the intestines via the hepatic portal vein to the liver. From there, the liver can process these nutrients further, regulating their levels and distributing them as needed throughout the body. However, the immediate destination right after absorption is indeed the bloodstream, facilitating the distribution of essential nutrients to various tissues and organs for energy, growth, and metabolic processes.

This underscores the essential role of the bloodstream in nutrient transport following the absorption phase in digestion.
