Hemoglobin is a molecule that attaches to ___________ and carries oxygen.

erythrocytes
leukocytes
monocytes
thrombocytes

The correct answer is: erythrocytes

Hemoglobin, a protein found in red blood cells, is responsible for transporting oxygen from the lungs to body tissues. Red blood cells, also known as erythrocytes, contain hemoglobin in high amounts and aid in the delivery of oxygen to the body's cells. Therefore, options B, C, and D, which refer to white blood cells (leukocytes), monocytes, and platelets (thrombocytes) respectively, are incorrect because they do not play a role in oxygen transport. Hemoglobin is specifically found in erythrocytes and is essential for its function as oxygen carrier.
