In our red blood cell, hemoglobin is present which carries oxygen to our body's organs and tissues and transports carbon dioxide from our organs and tissues back to our lungs. Hemoglobin is a protein molecule. The study of blood, blood disease, and blood-forming organ are called hematology. So take this quiz and know more about the hemoglobin structure and function.
