How does hydration affect the integumentary system?

Hydration plays a crucial role in maintaining the health and functionality of the integumentary system, particularly the skin. Adequate hydration helps to prevent dryness, which is essential for preserving the skin's barrier function. When the skin is well-hydrated, it remains supple and resilient, which can enhance its ability to protect against environmental damage and pathogens.

Furthermore, hydration supports skin cell turnover and repair processes, facilitating the healing of minor wounds and maintaining overall skin health. Well-hydrated skin is also less prone to developing conditions such as eczema or dermatitis, which can be exacerbated by dryness. Therefore, sufficient hydration is vital for sustaining various physiological functions of the skin, making option B the most accurate statement regarding hydration's effects on the integumentary system.
