How does compression help reduce swelling after an injury in the integumentary system?

• A. By increasing blood flow to the injured area
• B. By limiting the accumulation of fluid in the tissues
• C. By promoting the production of new skin cells
• D. By stimulating nerve endings to reduce pain

Answer: (B)

Verified step by step guidance

1. Understand the role of the integumentary system: The integumentary system includes the skin, hair, nails, and associated glands. It serves as a protective barrier and plays a role in fluid regulation and healing after injury.
2. Recognize the physiological response to injury: When an injury occurs, the body initiates an inflammatory response. This includes increased blood flow to the area, which can lead to swelling due to fluid accumulation in the tissues.
3. Learn how compression works: Compression applies external pressure to the injured area, which helps limit the movement of fluid from blood vessels into surrounding tissues. This reduces the accumulation of fluid and minimizes swelling.
4. Understand the mechanism of fluid regulation: Compression supports the lymphatic system by encouraging the drainage of excess fluid from the injured area back into circulation, preventing excessive buildup in the tissues.
5. Clarify the incorrect options: Compression does not increase blood flow, promote new skin cell production, or directly stimulate nerve endings to reduce pain. Its primary function is to limit fluid accumulation and reduce swelling.
