When soluble substances go through the wall of the small intestine in the blood?

When soluble substances pass through the wall of the small intestine into the blood, they are absorbed primarily through the intestinal villi, which increase the surface area for absorption. Nutrients such as glucose, amino acids, and certain vitamins enter the bloodstream via capillaries within the villi. This process is crucial for delivering essential nutrients to the body's cells for energy, growth, and repair. The absorbed substances then travel to the liver for further processing before being distributed throughout the body.
