WebFeb 11, 2024 · Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count (anemia). WebHemoglobin carries oxygen from the lungs to the tissues. Myglobin is the oxygen storage protein of the muscle. The richest source of myoglobin is the muscle of aquatic diving mammals, such as seals or whales, since these tissues need a very rich store of oxygen to see them through long anoxic periods during a dive.
