Answer :
Answer:
The effects of senescence on the integumentary system include:
- Graying hair: As individuals age, the production of melanin decreases, leading to the loss of pigment in hair follicles and the appearance of gray or white hair.
- Loss of skin elasticity: Over time, the skin loses its ability to stretch and recoil due to a decrease in collagen and elastin production, resulting in sagging and wrinkles.
- Thickening of collagen fibers: Senescence can lead to an accumulation of collagen fibers in the dermis, contributing to the thickening and stiffening of the skin.
The other options listed do not typically result from senescence on the integumentary system:
- Increased regeneration: Senescence generally decreases the regenerative capacity of the skin.
- Improved thermoregulation: Aging may impair thermoregulatory mechanisms due to changes in sweat gland function and blood flow regulation.
- Rosacea: While rosacea is a skin condition that can occur at any age, it is not directly associated with senescence on the integumentary system.
