Which of the following changes in aging skin contribute to increased susceptibility to infections? Select all that apply. decrea
sed number of functioning melanocytes decreased size of sebaceous glands decreased number of Langerhans cells decreased collagen synthesis macrophages become less efficient phagocytes
The first option is false. Melanocytes are cells that are responsible for the production of melanin throughout the skin of the body which affects the skin color.
The second option is also false. The Sebaceous glands are located at the end of the hairs on the skin and are responsible for producing oil throughout.
The third option is correct because langerhans cells are responsible for producing antigen throughout the skin and they are a part of the skin's immune system.
The following changes in aging skin contribute to increased susceptibility to infections.
The macrophages become less efficient phagocytes.
Decreased number of Langerhans cells.
The decreased collagen synthesis.
Explanation:
There are various factors which decreased the over all power or capacity of the human body to defend itself, as the defense mechanism of the body slows down with the ever increase in age of the living being, as the organ may tire out and they are no more present in the same active mood as they were once working inside the living being body. While, they require more care for obtaining the same level of efficiency and power.
With the ever lasting age of the living beings the macrophages also loses there abilities to work the same as they were once in a more active form fighting against the pathogens and other foreign particles.
While, imbalance inside the level of the as whole insulin and glucagon is greatly effected by the aging factor of the living being, as these hormones are more related to the number of Langerhans inside the pancreas.
