for diseases to enter the body they must penetrate the skin
The skin is selectively permeable. That means that only certain things are allowed in and out of the body through the skin.
The skin is very dry compared to the inside of the body and many pathogens do not grow well there. The skin also sheds all the time carrying the pathogens with the shed dead cells.

The pores on your skin help to prevent harmful pathogens from entering. Pathogens cause disease, infection and Cancer. By keeping these pathogens out, this is how pores protect you.
Yes! Skin is your initial defense when fighting pathogens (germs) It is very dry (for a pathogen) on the top layers, so pathogens cannot grow on the surface of your skin. Skin also is a bit acidic - it is about PH 6 or 5, which helps prevent things from growing or living on the skin to long. It is also thick, so pathogens can't get through.
The tissue under skin helps you by protecting what is below the skin, so not only do pathogens and other things have to get through your skin, they have to get through this layer of protective tissue also.
yes
Yes. That is one of the main functions of skin.
acidic environment
the skin keeps out most pathogens
The skin den the second layer is the phagocyte. These are the barriers of the skin.
true
Because the skin protects you. It 'keeps out the dirtybugs' as my grandma likes to say.
The integumentary system (skin) blocks the entrance of pathogens and prevents the loss of water.
The first line of immune defense is the skin and mucus membranes. Skin acts as a physical barrior, blocking pathogens from entering. Mucus wihin the nasal cavity blocks some of the pathogens from entering the body. Cilia also aid in protectiong by acting as a barrior as well. There is also mucus lining the bronchial tubes, which like other mucus, blocks pathogens.
