The digestive system absorbs the glucose in the small intestine. Then the glucose is now in the blood stream. The respiratory system needs the glucose to make energy. The circulatory system gets the oxygen pumped into the body. And now there are glucose and oxygen in the bloodstream. Now the respiratory system, the glucose and the oxygen react with each other and there is now energy. http://wiki.answers.com/Q/How_is_the_circulatory_respiratory_and_digestive_system_connected#ixzz1dAflkUjp
The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveoli is taken up by the blood in the alveolar blood vessels, to be transported to all the cells in the body. From www.wikipedia.com
Villus capillaries collects amino acids and simple sugars taken up by the villi into the blood stream. Villus lacteals (Lymph capillary) collect absorbed chylomicrons, which are lipoproteins composed of triglycerides, cholesterol and amphipathic proteins, and are taken to the rest of the body through the Lymph fluid.
Villi also help the intestines to move food along the digestive pathway.
