Erythrocytes, also known as red blood cells, are the most important blood cells that make up the majority of all blood cells. They are responsible for transporting oxygen from the lungs to all body tissues and transporting carbon dioxide back to the lungs. Erythrocytes are anucleated and have a red color due to hemoglobin, which is a protein capable of binding to oxygen molecules. They are formed in the bone marrow and live for about 120 days, after which they are destroyed and replaced by new erythrocytes.
