Erythrocytes are microscopic cells also called:

Erythrocytes are indeed commonly known as red blood cells. Their primary function is to transport oxygen from the lungs to the body's tissues and carry carbon dioxide back to the lungs for exhalation. The presence of hemoglobin, a protein that binds to oxygen, is what gives these cells their characteristic red color.

Platelets are involved in blood clotting and are not the same as erythrocytes. White blood cells are part of the immune system and play roles in defending the body against infection. Plasma is the liquid component of blood that carries cells and other substances but is not a type of cell itself. Understanding the specific role and characteristics of erythrocytes helps clarify their importance in the circulatory system and overall health.
