There is actually a disease called Sickle
Cell Anemia in which the red blood cells cannot
carry oxygen well which causes the blood cells
to curve like a crescent moon. Curved red blood
cells cannot move easily and can become stuck in
small blood vessels, blocking them. Once the
blood vessel is blocked, blood cannot get to
that part of the body. Organs then don´t receive
normal blood flow which causes them to become
damaged over time. This is a very serious
disease and there currently is not known cure -
we don´t know how to reshape red blood cells
once they are damaged.
