Detailed explanation-1: -Haemoglobin is the red pigment which carries oxygen in the blood. RBC contain haemoglobin in it. Haemoglobin is an iron-containing protein that carries oxygen from the lungs to the body.

Detailed explanation-2: -Hemoglobin carries oxygen to the cells. This respiratory pigment of the blood transports oxygen and carbonic anhydride, regulates pH balance, gives rise to bilirubin, and gives the blood its red color.

Detailed explanation-3: -Oxygen is one of the substances transported with the assistance of red blood cells. The red blood cells contain a pigment called haemoglobin, each molecule of which binds four oxygen molecules. Oxyhaemoglobin forms. The oxygen molecules are carried to individual cells in the body tissue where they are released.

Detailed explanation-4: -Oxygen is carried by a red pigment called haemoglobin present in the red blood cells.

Detailed explanation-5: -Hemoglobin itself is a compound of a colorless protein, globin, and an iron porphyrin pigment. In general the pigments formed by the combination of iron with the various porphyrins are called hemes.
