Questions
- Identify 3 ways in which the skin protects the body.
Answers
- The skin serves as a crucial barrier for the body in several ways:
- Protection from External Injury: The skin acts as the first line of defense against physical injuries. It absorbs shocks and prevents cuts, bruises, and abrasions from affecting the internal organs and tissues.
- Barrier Against Micro-organisms: The skin prevents the entry of harmful pathogens such as bacteria, viruses, and fungi. It does this through its outer layer, which is tough and impermeable, acting as a shield against infections.
- Protection from Ultraviolet Rays: Melanin, a pigment produced by skin cells, provides natural protection against the harmful effects of ultraviolet (UV) radiation from the sun. It absorbs and dissipates UV rays, reducing the risk of skin damage and skin cancer.
