How are nutrients moved from the digestive system to the circulatory system?

Products of carbohydrate digestion (simple sugars) and products of protein digestion (amino acids) move through brush border cells, diffuse through the interstitial fluids inside the villus, then enter a capillary. Products of fat digestion (triglycerides) also cross the brush border cell and interstitial fluid, but they enter lymph vessels, which eventually carry them to the blood.
