In humans, what is the typical shape of a mature red blood cell (erythrocyte)?
A
Spherical cell
B
Long, branched neuron-like cell
C
Cuboidal cell
D
Biconcave disc
Verified step by step guidance1
Recall the primary function of mature red blood cells (erythrocytes), which is to efficiently transport oxygen throughout the body.
Understand that the shape of erythrocytes is specialized to maximize surface area for gas exchange and to allow flexibility when passing through narrow capillaries.
Identify that the typical shape of a mature red blood cell is a biconcave disc, meaning it is round and flattened with a concave depression on both sides.
Recognize that this biconcave shape increases the surface area-to-volume ratio, enhancing oxygen diffusion and allowing the cell to deform easily.
Compare this shape to the other options (spherical, neuron-like, cuboidal) and note that these do not provide the same functional advantages for oxygen transport.
