Thus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration. Osmotic Pressure. The net pressure that drives reabsorptionâthe movement of fluid from the interstitial fluid back into the capillariesâis called osmotic pressure (sometimes referred to as oncotic pressure).
Capillaries move blood the entire length of the villus. When the villi absorb nutrients like water soluble vitamins, amino acids and sugars, they are transported into the capillaries for distribution and use throughout the body. The villi also contain vessels called lacteals. Lacteals are part of the lymphatic system. Any fats, fat soluble vitamins and excess liquids absorbed by the villi are first moved into the lymph fluid circulation before being emptied into the blood stream. The villus structures are also involved in digestion.
