What is the relationship of skin and immune system?

Answer 1

It provides natural immunity by providing a barrier that keeps out pathogens and other harmful materials. It is slightly acidic which makes it a deterrent to bacteria. It secretes sebum which helps lubricate and coat the skin, providing an added layer of protection.

Answer 2

Think of it as a wall, and behind it are the defenders (white blood cells). This is somewhat simplistic, but its the basic idea. Your epidermis is there to keep most things out, so you could even take the metaphor as far as to say that anything sharp enough to break it is like a battering ram for germs. Since all the skin on the outside is dead, germs cannot attack it the way they attack the rest of your body. They have to find a way in first, which they are doing all the time, but they'd have a much easier job of it if it weren't for your epidermis.

Answer 3

it keeps pathogens out

Pretty Kitty edit:
well it doesn't just keep that out it keeps a lot of things in but it keeps a lot of harmful things out. so yeah i am gonna do a project on the skin helping the immune system so any more hints tell me

Answer 4

Without it things (germs, etc.) could get in. It's kind of an obvious one there. An example I could think of is getting a cut - if it is large or gets infected that part of your immune system is compromised and then the infection could travel to the rest of your body.

Answer 5

the skin is the first line of defense agaist infection. any type of cut, open wound or abrasion compromises your ability to prevent infection. bacteria can enter the body through the open wound and enter the boodstream. that's when the immune system kicks in, sending white blood cells in the form of Macrophages &

Phagocytes to surround and destroy the invader.

Answer 6

The skin is one of the first defense mechanisms for the immune system.

Langerhans cells (dendritic cells)
