what is crenation
Crenation is a phenomenon which occurs when cells of animal origin are exposed to a hypertonic solution, meaning that the solution which bathes the cells has a high concentration of solutes.In crenation, the cells shrink and their shapes become distorted, often with a ruffled or scalloped edge.The change in cell shape can be seen in microscopy of the cells, and can be a sign that someone is experiencing a medical problem. These cells may die as a result of impairments in cell function.n crenation, the cells shrink and their shapes become distorted, often with a ruffled or scalloped edge.
