Partially digested food enters the small intestine in liquid form where it is turned into substances that can be used by cells. The blood vessels along the small intestine walls absorb these substances and blood cells are then able to transport these to the body's cells and tissues.he relationship between the circulatory and digestive system is mainly basic-without one, the other cannot function properly. The blood absorbs (takes in) nutrients in the small intestine. The blood help transport these nutrients so that it can be used by the cell tissues in the body.
How Do Villi Absorb Nutrients? When food is broken down in the stomach, it forms a substance called chyme, which is a slurry of nutrients. When that slurry passes into the small intestine, it comes into contact with the villi. The carbohydrates and proteins in the chyme enter the bloodstream passively via the vein and artery. The fat is absorbed by the lacteal into the lymphatic system, which eventually empties into the bloodstream. In a process called active transport, specialized intestinal cells of the villi allow the passage of B-12, iron and calcium into the bloodstream.
