The small intestine, a vital part of the digestive system, is where most nutrient absorption occurs. Villi lining its walls absorb nutrients into capillaries of the circulatory system and lacteals of the lymphatic system [2]. Organic nutrients absorbed into the blood capillaries include monosaccharides, amino acids, water-soluble vitamins, and minerals [2, 3, 4, 6].

The human body contains an extensive network of microscopic blood vessels called capillaries, which are responsible for the critical exchange of substances at the cellular level. As the smallest blood vessels, what do blood capillaries absorb from the surrounding tissues, and how is this process regulated? This article will explore the complex mechanisms that govern capillary absorption and exchange, detailing the specific substances involved.
