Which portion of the blood carries oxygen to and wastes away from body tissues?

Explanation:
Gas transport is the main job of red blood cells. They are packed with hemoglobin, which binds oxygen in the lungs and releases it to tissues that need it. They also pick up carbon dioxide, a waste product from cells, and carry it back to the lungs to be exhaled. This gas-carrying function is what makes red blood cells the key component for delivering oxygen to tissues and removing wastes, while platelets handle clotting, white blood cells fight infection, and plasma is the fluid that carries nutrients, hormones, and wastes.
