Red blood cells (RBCs), also known as erythrocytes, are the cells present in the highest quantity in blood.
RBCs are crucial for transporting oxygen throughout the body. Their high concentration, typically ranging from 4 to 6 million cells per cubic millimeter of blood, ensures efficient oxygen delivery to tissues and organs. While other blood cells like white blood cells (leukocytes) and platelets (thrombocytes) are also vital for immune function and blood clotting, respectively, their numbers are significantly lower than that of red blood cells.
In summary, red blood cells are the most abundant type of cell found in human blood.
