|
The biconcave shape of RBCs is beneficial because it:
|
|
allows more space for the mature RBCs to accommodate the nucleus.
|
|
|
makes the RBCS more flexible so they can pass and bend through the smaller bloodvessels more easily.
|
|
|
prevents diapedesis of RBCs through the walls of the blood capillaries.
|
|
|
decreases the ratio of cell surface area to volume of the cell and allows for greater functionality
|
Explanation:
Detailed explanation-1: -RBCs are also biconcave in shape; this shape increases their surface area for the diffusion of oxygen across their surfaces.
Detailed explanation-2: -“The myosin pulls on the actin to provide tension in the membrane, and then that tension maintains the biconcave shape.”
