Hemoglobin (/ËhiËmÉËÉ¡loÊbáµ»n, ËhÉ-, -moÊ-/); also spelled haemoglobin and 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.
Updated February 28, 2017. Hemoglobin is a protein that is contained within red blood cells (RBCs). Hemoglobin is the part of the red blood cell that carries oxygen to, and carbon dioxide away from, the cells in the body. Without the right amount of hemoglobin in the red blood cells, the cells of the body will not be able to receive enough oxygen.
