Question

which component of the blood transports both oxygen and carbon dioxide?
o leukocytes
o erythrocytes
o basophils

Explanation:

Erythrocytes, or red - blood cells, contain hemoglobin which binds to oxygen in the lungs and releases it in the tissues. They also carry some carbon dioxide back to the lungs. Leukocytes are part of the immune system and basophils are a type of leukocyte involved in immune responses, not gas transport.

Answer:

Erythrocytes
