Question

Compare the size of both types of red blood cells and siclke shaped red blood cells and explain how this affects their efficiency in carrying oxygen.

Answer 1

Answer:

When they lose their oxygen, they form into the shape of a sickle or crescent, like the letter C. These cells stick together and can't easily move through the blood vessels. This can block small blood vessels and the movement of healthy, normal oxygen-carrying blood. The blockage can cause pain.
