Verified step by step guidance

Understand the role of erythrocytes: Erythrocytes, or red blood cells, are specialized cells in the blood primarily responsible for transporting gases throughout the body.

Identify the main component of erythrocytes: Hemoglobin is the protein in red blood cells that binds to oxygen in the lungs.

Consider the process of oxygen transport: Oxygen binds to hemoglobin in the lungs and is then released to body tissues where it is needed for cellular respiration.

Evaluate the options: Compare the primary function of erythrocytes with the given options. Consider which option aligns with the role of transporting oxygen.

Conclude with the correct function: Recognize that the primary function of erythrocytes is to transport oxygen from the lungs to body tissues, distinguishing it from other functions like regulating blood pressure, producing antibodies, or initiating blood clotting.
