Show answer & explanationAnswer & explanation
Correct answer: A. Integumentary system; protecting the body from environmental damage and regulating hydration.
The integumentary system, which includes skin, hair, and nails, is responsible for protection and hydration. Dry, flaky skin and brittle nails are direct indicators of issues within this system's primary functions.
Why the other options are wrong
- B. The nervous system controls sensations and muscle movement, and while it influences glandular activity, it's not the primary system for the structural integrity and hydration of skin and nails.
- C. While the circulatory system transports nutrients, it is not the primary system responsible for the structure and direct protection provided by skin and nails.
- D. The endocrine system produces hormones that influence many body functions, including skin and nail health, but it's not the primary system responsible for their physical manifestation and direct protective role.
Integumentary System Functions
The integumentary system, comprising skin, hair, and nails, serves as the body's outer protective barrier.
- Protects against environmental damage and pathogens.
- Regulates body temperature through sweating and insulation.
- Prevents water loss and aids in hydration.
- Synthesizes Vitamin D.
Memory trick: Integumentary is your 'outer shell' system.
