Blood plays an important role in our body. It carries oxygen from the lungs to all the other tissues in the body. It also carries nutrients to all parts of the body. Blood also transports special chemicals called hormones, that regulate certain body functions. Waste products produced during metabolism such as urea and uric acid are carried by the blood to the kidneys.There's a lot more.
