Final answer:
Cryosurgery is a medical procedure that uses extreme cold, not hot temperatures, to destroy tissue. The term itself indicates that cold is used (kryo means 'cold' in Greek), which is achieved through cryogenic liquids such as liquid nitrogen.
Step-by-step explanation:
The statement that in cryosurgery, extremely hot temperatures are used to destroy treated tissue is FALSE. Cryosurgery utilizes the application of extreme cold, not heat, to selectively destroy tissue. This medical procedure employs cryogenic liquids, such as liquefied nitrogen, which have a boiling point of 77 K at 1 atm. These cryogenic liquids are capable of destroying tissues with minimal blood loss by applying freezing temperatures that cause ice crystal formation within the cells, leading to cell death. The term 'cryosurgery' itself comes from the Greek kryo, meaning 'cold,' indicating the use of cold temperatures in the procedure.
