Why Golgi appretus absence in red blood cells?

Red blood cells (RBCs) lack a nucleus and many organelles, including the Golgi apparatus, to maximize space for hemoglobin, the protein responsible for oxygen transport. During their development, RBCs expel these organelles, which allows for greater flexibility and efficiency in their primary function. This adaptation is crucial for their role in navigating through narrow capillaries and effectively delivering oxygen throughout the body.
