Root Explanation

Perisarc is derived from the Greek "peri-" (meaning around) and "sarkos" (meaning flesh). The term refers to a protective layer or covering that surrounds the body of certain organisms, particularly in zoology.

Memory Tip

Think of something that covers or goes 'around' ('peri-') the 'flesh' ('sarkos') of an organism, which helps you remember that a perisarc is a protective layer.
