If the cells look normal, it means that they did not shrink or swell. This indicates that there was no net movement of water in or out of the cells, which would happen if the solution was either hypotonic (causing the cells to swell) or hypertonic (causing the cells to shrink). Therefore, the solution mixed with the blood was likely isotonic, meaning it had the same concentration of solutes as the blood.
