What are the Key Features of Red Blood Cells in Histology?
Red blood cells (RBCs) are biconcave, disc-shaped cells that lack a nucleus. In a healthy smear, RBCs appear uniform in size and shape, with a central pallor due to their biconcave shape. Variations in size (anisocytosis), shape (poikilocytosis), or color (polychromasia) can indicate pathologies such as anemia or other blood disorders.
