The+transport+system


 * The transport system** (circulatory system) is an organ system that passes nutrients, gases, hormones, heat, blood cells, oxygen, urea and carbon dioxide to and from cells in the body. The circulatory system is composed of the heart, blood vessels (veins, arteries, capillaries) and the blood (red blood cells, white blood cells, platelets, plasma). The circulatory system includes: the pulmonary circulation, a loop through the lungs where blood is oxygenated; and the systemic circulation, a loop through the rest of the body.
