Hemoglobin belongs to the organic group known as proteins. It is a complex protein composed of four polypeptide chains, each containing a heme group that binds oxygen. Hemoglobin's primary function is to transport oxygen from the lungs to the tissues and facilitate the return of carbon dioxide from the tissues back to the lungs. Its structure and function are crucial for the respiratory process in many organisms.
