Verified step by step guidance

Understand the term 'erythrocytes'—these are commonly known as red blood cells, which are specialized cells in the blood responsible for transporting oxygen throughout the body.

Recall the primary function of erythrocytes: they contain hemoglobin, a protein that binds oxygen in the lungs and releases it to tissues while also facilitating the transport of carbon dioxide back to the lungs.

Differentiate erythrocytes from other blood components: plasma proteins maintain osmotic pressure, white blood cells (leukocytes) are involved in immune responses, and platelets (thrombocytes) aid in blood clotting.

Eliminate incorrect options based on the definitions of plasma proteins, white blood cells, and platelets, ensuring the focus remains on the oxygen transport function of erythrocytes.

Confirm the correct answer: erythrocytes are red blood cells responsible for transporting oxygen, as this aligns with their structure and function in the circulatory system.
