**-Another name for the circulatory system is the __cardiovascular system.__ -Consists of the heart, blood vessels, and blood. -The circulatory system, or cardiovascular system, imports the needed substance to cells and imports the waste products apart from cells. -In addition to that, the blood contains cells that try to back off or fight the disease. -The circulatory system is mostly associated with blood.** -The circulatory system includes: the pulmonary circulation through the lungs wre blood is oxyenated and the systemic circulation through the body to provide oxygenated blood. - An average adult contains 5 to 6 quarts of blood which consits of red blood cells, white blood cells, and platelets**
 * -Blood helps carries substances to one part of the body to another (an example of this is oxygen from your lungs to other body cells are carried by blood.)**
 * -Another thing blood does is transfer the glucose to your cells and this to produce energy.****-The circulatory system has many other functions, one of the functions are that it picks up the waste from your cells.****-A example of this is when your cells break down glucose, they produce carbon dioxide as a waste product. Then the carbon dioxide passes from your cells into your blood.**
 * -The circulatory later on carries carbon dioxide to your lungs, where it is exhaled.**
 * -Another function of the circulatory system is to transfer cells that attack disease-causing microorganisms.**
 * -When this happens, you have a less chance to get sick.****-Say if you did get sick, these disease-fighting blood cells will kill the microorganisms and help you get well.** **-humans- have a closed cardioascular system (meaning that the blood never leaves the network of arteries, veins, and capillaries.)
