Hemoglobin: The Respiratory Pigment in Red Blood Cells - Understanding Oxygen Transport

The red blood cells or erythrocytes are specialized blood cells that contain the respiratory pigment hemoglobin. Hemoglobin is a protein that binds to oxygen in the lungs and transports it to various tissues and organs in the body. Each red blood cell contains millions of hemoglobin molecules, enabling the efficient transportation of oxygen throughout the body.
