👉 Cauterise, also known as dehydratation or dehydration, is a process in medicine and biology where cells are reduced to their essential components through heat, pressure, or other causes. It involves the removal of water from tissues by the destruction of damaged cellular structures. In medical terms, cauterisation refers to the method used to destroy any damage that has been caused to a tissue during an operation. This process is crucial in preventing infection and ensuring the success of surgeries.
