Explain the meaning of Haemolysis and crenation?

Answer 1

Haemolysis is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid . Crenationis the contraction or formation of abnormal notchings around the edges of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis.Crenation occurs because in a hypertonic environment, (that is, the cell has a lower concentration of solutes than the surrounding extracellular fluid), osmosis (the diffusion of water) causes a net movement of water out of the cell, causing the cytoplasm to decrease in its volume. As a result the cell shrinks.
