Final answer:
Amputation is the surgical removal of limbs, fingers, or toes and is distinct from procedures like angioplasty and coronary bypass surgery, which treat narrowed or blocked arteries.
Step-by-step explanation:
When a person's limbs, fingers, or toes are removed during surgery, the procedure is called an amputation. This surgical process is essential in preventing the spread of gangrene, infection, or as a result of severe tissue damage that leaves limbs nonviable. On the other hand, procedures such as angioplasty or coronary bypass surgery are performed to treat conditions like atherosclerosis, where arteries are narrowed or blocked. Lifestyle changes and medication can also accompany surgical intervention in managing the underlying atherosclerosis, as it poses a higher risk of myocardial infarction or stroke.
It can be performed for several reasons, such as to treat cancer, prevent infection, or improve quality of life. For example, if a person has a severe injury to their leg that cannot be repaired, amputation may be necessary to prevent further complications.
