This function works together with other organs and body systems to support everyday health.
Body Systems
Integumentary System
Introduction
The integumentary system includes the skin, hair, nails, sweat glands, and related structures. It forms a protective barrier and helps regulate temperature, sensation, and vitamin D production.
This information is educational and is not intended to diagnose medical conditions. Symptoms can have many causes, and persistent or concerning symptoms should be evaluated by a qualified healthcare professional.
Primary Functions
Regulating temperature and supporting sensation
This function works together with other organs and body systems to support everyday health.
Contributing to wound healing and vitamin D production
This function works together with other organs and body systems to support everyday health.
Signs of Healthy Function
- Skin that heals normally
- Hair and nails following their usual growth patterns
- No persistent or rapidly changing lesions
Healthy function looks different across ages, disabilities, chronic conditions, and individual baselines. Changes from your usual function can matter more than comparison with someone else.

Nutrient-Rich Foods
Protein, vitamins A, C, D, E, zinc, iron, biotin, and essential fats support normal skin, hair, and nail function.
