A bright-red chemical complex of hemoglobin and oxygen that transports oxygen to the tissues.


(ˌɒk sɪˈhi məˌgloʊ bɪn, -ˈhɛm ə-)

a chemical compound of hemoglobin and oxygen that gives arterial blood its bright red color.


The compound formed when a molecule of hemoglobin binds with a molecule of oxygen. In vertebrate animals, oxyhemoglobin forms in the red blood cells as they take up oxygen in the lungs.
