Along with having smooth edges and lacking organelles, red blood cells are also specialized to have a concave shape. How does the
shape of a red blood cell help it to perform its specific function in the human body?
A.
This shape increases the surface area of the cell, which allows it to bind and transport oxygen more easily.
B.
This shape decreases the volume of the cell, which allows the cell to cross semipermeable membranes more easily.
c.
This shape increases the volume of the cell, which allows it to store more carbon dioxide for transport.

This shane decreases the surface area of the cell, which makes the cell less susceptible to infection.
