The circulatory system and immune system serve the same, yet complementary purpose, to keep the entire body alive. The circulatory system does this by delivering oxygen from the lungs to every organ and cell in the body. The immune system does this by consuming foreign substances before they can damage the body. The connection between the circulatory system and immune system lies in the fact that the immune system travels through the entire body, inside the circulatory system. The circulatory system has three major components: the heart, the lungs, and blood vessels.
The digestive system work with the circulatory system by immediatly in the small intestine absorb the nutrients from our food and to put them to use but this is after the nutrients are broken down further by the liver (via the heptic portal) which is the first port of call for nutrients absorbed from the intestine.he main way in which the respiratory and the circulatory system work together is that the heart send blood to the lungs, which is then oxygenated, so the blood can then be sent to the rest of the body (after being pumped back through the heart).
