<P> Hemoglobin ( American ) or haemoglobin ( British ) ( / ˈhiːməˌɡloʊbɪn , ˈhɛ - , - moʊ - / ) ; abbreviated Hb or Hgb , is the iron - containing oxygen - transport metalloprotein in the red blood cells of all vertebrates ( with the exception of the fish family Channichthyidae ) as well as the tissues of some invertebrates . It has the formula C H O N S Fe . Hemoglobin in the blood carries oxygen from the respiratory organs ( lungs or gills ) to the rest of the body ( i.e. the tissues ) . There it releases the oxygen to permit aerobic respiration to provide energy to power the functions of the organism in the process called metabolism . </P>
