According to Santa Barbara City College, red blood cells' biconcave shape gives them a vastly greater surface area than a spherical cell of similar volume, which allows them to absorb oxygen more efficiently.

Red blood cells can neither reproduce nor replenish cellular machinery, and they die off in large numbers over time.Full Answer >
