Red blood cell that transports oxygen and carbon dioxide within the bloodstream is called what?

Red blood cell that transports oxygen and carbon dioxide within the bloodstream is called what?

• A. Erythrocyte
• B. Leukocyte
• C. Platelet
• D. Lymphocyte

Answer: (A)

Gas transport in the blood is the job of red blood cells, and the cell type that specializes in carrying both oxygen and carbon dioxide is the erythrocyte. Hemoglobin inside these cells binds oxygen in the lungs and releases it to tissues, while also helping to move carbon dioxide from tissues back to the lungs to be exhaled. This dual transport role distinguishes erythrocytes from other blood cells, such as leukocytes, which defend against infection, platelets, which help with clotting, and lymphocytes, which are a specific type of immune cell.
