Red blood cells have a circular biconcave shape to increase surface area to volume ratio for faster absorption of oxygen in the bloodstream.
Red blood cells (erythrocytes) are described as being biconcave. This unique shape increases their surface area for oxygen absorption and allows them to deform as they pass through narrow capillaries. The biconcave structure contributes to their efficiency in transporting oxygen from the lungs to tissues throughout the body.
Red blood cells
A red blood cell is disc-shaped with a thin center and thicker edges, resembling a biconcave disc. This shape allows for flexibility and more surface area for oxygen exchange.
