Verified step by step guidance

Begin by understanding the primary function of erythrocytes, which is to transport oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs.

Recognize that erythrocytes, also known as red blood cells, are produced in the bone marrow, not the liver. This is a key point in distinguishing their origin.

Note that mature erythrocytes lack a nucleus and mitochondria, which is an adaptation to maximize space for hemoglobin, the protein responsible for oxygen transport.

Understand that erythrocytes are not primarily involved in the immune response; this role is mainly fulfilled by leukocytes, or white blood cells.

Conclude that the correct statement about erythrocytes is their responsibility for transporting oxygen in the blood, facilitated by the presence of hemoglobin.
