WebbA number of pathological mutations result in the red blood cell adopting a spherical shape as opposed to the biconcave disc profile. The sphere has a smaller moment of inertia when compared to the discocyte, as much of the mass is distributed round the centre. The spherocyte is hence much more prone to rotation during flow in the large vessels. WebbAns= Generally the shpe of RBC of frog is elliptical in shape and contain nucleus so also called nuclted RBC.

Webb17 jan. 2024 · Red blood cells: Human red blood cells (6–8μm) RBCs are disc-shaped with a flatter, concave center. This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. WebbThese are red blood cells (RBCs). Some look like they have a hole in the middle, but this is due to the thin area of the biconcave shape that allows for flexibility and to increase surface area.
