27. This is a list of some of the problems that occur to the integumentary system during aging. Explain what is actually happening to cause these problems. a. Reduced bone strength – As a human gets older their bones get weaker due to their bone reabsorbing calcium.

b. Hair turning grey or white –

As we get older the melamine in our hair that make it healthy gets reduced which make our hair turn grey or white.

c. Increased likeliness of skin injury and infection Older people need to watch out for any changes in their health and make sure what we put in our mouth is appropriate for our health when we get older.
