Erythrocyte physiology · Physiology

Which property allows erythrocytes to pass through narrow capillaries?

  1. Their exceptionally high hemoglobin content
  2. Biconcave shape and membrane flexibility
  3. Presence of a small central nucleus
  4. Their large intracellular stores of ATP
Show answer and explanation

Correct answer: Biconcave shape and membrane flexibility

Erythrocytes are highly flexible due to their membrane structure and biconcave shape. This allows them to deform and pass through capillaries.
