What is an abscess?

Explanation:
An abscess is a localized collection of pus that forms within a tissue space as the body tries to contain an infection. Pus is made up of dead white blood cells (primarily neutrophils), bacteria, and tissue debris, and the body often walls off this material with a fibrous capsule, creating a distinct, enclosed cavity. This differentiates it from simply swollen tissue or a noninfected lesion. This concept explains why the description “an accumulation of pus within an enclosed tissue space” is the best choice. Other options describe different processes: an enlarged lymph node is lymphadenopathy, not a pus-filled cavity; a collection of dead tissue points to necrosis, which may occur with tissue injury but is not pus-filled; and a skin blister filled with clear fluid is a vesicle, not pus.
