Final answer:
An abscess and a granuloma are both ways the body attempts to isolate or 'wall off' an infection, representing the immune system's efforts to contain and control the spread of the infection.
Step-by-step explanation:
The body's attempt to isolate or "wall off" an infection is best exemplified by both an abscess and a granuloma. An abscess is a localized collection of pus that helps sequester an infection, while a granuloma is a small area of inflammation due to tissue injury or infection, where the immune system attempts to isolate foreign substances that it is unable to eliminate. These are biological mechanisms by which the body attempts to contain infections and prevent their spread.
