Within every cell (except red blood cells) is a nucleus -- a sphere-like structure separated from the rest of the cell by a membrane. The nucleus acts as the cell's control center, regulating its ...

Researchers at the Department of Biomedicine at Aarhus University are the first in the world to uncover the precise structure ...

Red blood cells are disc-shaped cells with no nucleus. They are very small but their flattened shape gives a relatively large surface area which allows rapid diffusion of oxygen.

The red cell of vertebrates is a remarkably effective device for the transport of oxygen to other cells. Many workers seek to elucidate the intricate molecular structure of its surface ...

Red blood cells carry oxygen from the lungs to every other organ, and blood-forming stem cells must make about 200 billion new red blood cells each day to keep the oxygen flowing. For many years, ...
