    en.wikipedia.org/wiki/Hemoglobin

    Hemoglobin (haemoglobin, [a] Hb or Hgb) is a protein containing iron that facilitates the transportation of oxygen in red blood cells. Almost all vertebrates contain hemoglobin, [ 3 ] with the sole exception of the fish family Channichthyidae . [ 4 ]

    A:Normal red blood cells are shown flowing freely in a blood vessel on the top of the diagram. The inset image shows a cross-section of a normal red blood cell with normal hemoglobin. B:Demonstrates abnormal, sickled red blood cells blocking blood flow in a blood vessel (vaso-occlusive crisis). The inset image shows a cross-section of a sickle ...

    Hemoglobin (Hb) is the primary vehicle for transporting oxygen in the blood. Each hemoglobin molecule has the capacity to carry four oxygen molecules. These molecules of oxygen bind to the globin chain of the heme prosthetic group. [1] When hemoglobin has no bound oxygen, nor bound carbon dioxide, it has the unbound conformation (shape). The ...

  9. Blood - Wikipedia

    Carbon monoxide, for example, is extremely dangerous when carried to the blood via the lungs by inhalation, because carbon monoxide irreversibly binds to hemoglobin to form carboxyhemoglobin, so that less hemoglobin is free to bind oxygen, and fewer oxygen molecules can be transported throughout the blood. This can cause suffocation insidiously.
