Question

which age - related change(s) occur(s) in the integumentary system? (select all that apply.)
skin thins and becomes transparent.
skin becomes dry.
elastic fibers and adipose tissue diminish.
hair thickens as follicles decrease.
thinned skin leads to cold intolerance.

Explanation:

1. With aging, the epidermis and dermis thin, and blood vessels become more visible, making skin appear transparent.
2. Sebaceous gland activity decreases with age, reducing oil production and causing dry skin.
3. Degradation of elastic fibers and loss of subcutaneous adipose tissue are common age-related integumentary changes, leading to sagging and loss of cushioning.
4. As follicles decrease, hair becomes thinner, not thicker, so this is incorrect.
5. Thinned skin and loss of adipose tissue reduce insulation, leading to increased cold intolerance.

Answer:

A. Skin thins and becomes transparent.
B. Skin becomes dry.
C. Elastic fibers and adipose tissue diminish.
E. Thinned skin leads to cold intolerance.
