Explanation:
Blood, fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process.
Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.
Blood contains many cell types, but the distinctive red color comes from the aptly named red blood cells (RBCs). RBCs have their rich red color because of a vitally important iron-containing protein called hemoglobin. The protein picks up oxygen molecules as the blood exchanges gases in the lungs.
