Quizplus · Accepted Answer

Red blood cells, also known as erythrocytes, are the most abundant cells in the blood and account for almost half of its volume. They are responsible for carrying oxygen from the lungs to the rest of the body and transporting carbon dioxide back to the lungs to be exhaled. Leukocytes (white blood cells), platelets (thrombocytes), and megakaryocytes are also present in the blood but in much smaller quantities compared to red blood cells.
