Biconcave shape to provide a large surface area for the diffusion of oxygen. No nucleus to provide more space for haemoglobin ...

epithelial cell shapes and eye lens transparency and mechanics. The biconcave disk shape and deformability of mammalian red blood cells (RBCs) rely upon the membrane skeleton, a viscoelastic network ...

Scientists have developed a way of assessing the ability of red blood cells to deliver oxygen by measuring their shape. This test could improve specialist transplant and transfusion practice as well ...
