Although blood cells serve multiple roles in the body and have complex interactions with other cellular materials, most synthetic blood products have aimed to just stick to the bare basics — shuttling oxygen from the lungs to different vital organs and then bringing carbon dioxide back to the lungs to be exhaled.
