Hemoglobin's primary function is to bind and carry oxygen, with a smaller capacity to carry carbon dioxide. Specifically, hemoglobin binds to oxygen in the lungs and carries it to tissues throughout the body, where it is released for use in cellular respiration. Hemoglobin also binds to carbon dioxide produced by cells and carries it back to the lungs to be exhaled. However, the majority of carbon dioxide in the blood is carried in the form of bicarbonate ions, not bound to hemoglobin.
