Which term describes maggot therapy debridement focusing on necrotic tissue removal?

• A. They heal wounds by closing edges
• B. They dry wounds by absorbing moisture
• C. They debride by consuming necrotic tissue and secrete antimicrobial enzymes
• D. They deliver antibiotics

Answer: (C)

Maggot therapy debridement works through two main actions: the maggots actively feed on and remove necrotic tissue, and they secrete enzymes and antimicrobial substances that help break down dead tissue and suppress bacteria. This combination directly accomplishes debridement by clearing nonviable tissue while helping to clean the wound bed, which is the essential goal of this therapy.

So the description that captures both parts—consuming necrotic tissue and secreting antimicrobial enzymes—is the best match. It isn’t about closing wound edges, drying the wound by absorbing moisture, or delivering antibiotics, which are not the primary mechanisms of maggot-assisted debridement.
