__The Circulatory System__
The circulatory system is one of the the ten major bodily systems. The circulatory system works kind of like a highway carrying nutrients and oxygen around the body. The major organs of circulatory system are the heart,veins,arteries and capillaies. The circulatory systems job is too get nutrients and oxygen around the body and it does this by work of the heart. The heart pumps and takes in blood. The right part of your heart which contains the right ventricle and right atrium takes in deoxygenated (blue) blood. Which it will later pump out toward the lungs. To get there it will travel by the veins. Once at the lungs the blood will travel through capillaries witch are tightly wrapped around little oxygen holding sacs called alveoli. As the blue blood cells pass the alveoli they give away there Carbon dioxide and absorb oxygen, this process is often referred to as the gas exchange. After exchanging gases the blood becomes oxygenation (red) blood and travels the rest of the way through the cappilary to an artery which will then go to the right side of the heart. In the right side of the heart the blood the blood goes to the right ventrical via left atrium. To the rest of the body. Where it can deliver oxygen and nutrients to the muscles.
