What blood cells are referred to as erythrocytes?

Erythrocytes are the scientific term for red blood cells, which are crucial components of the circulatory system. They are primarily responsible for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide back to the lungs for exhalation. This process is facilitated by hemoglobin, a protein found in red blood cells that binds to oxygen.

Understanding the role and structure of erythrocytes helps clarify why they are vital for maintaining the body's metabolism and overall health. In contrast, white blood cells play a key role in the immune system, platelets are involved in blood clotting, and plasma cells are a type of white blood cell that produces antibodies. These other blood components have distinct functions different from the oxygen transport role of erythrocytes.
