You haven't given us the diagrams, but in case you're asking about the shape, imagine this: a disc, with a sunken centre, starting to resemble a donut.
In a low salt solution, the cells would start to absorb water, thus, inflating, up to the point of resembling spheres, and even bursting in the end. In case of a salty solution like the one you proposed, blood cells would lose water and would become a bit amorphous. In the attached pic you can see a standard blood cell (on the left), and a cell submerged in a salty solution (on the right).
