Answer:

Skin, mucous membranes, acid skin

Step-by-step explanation:

Natural barriers and the immune system defend the body against organisms that can cause infection. Natural barriers include the skin, mucous membranes etc. The normal flow of urine washes out microorganisms that enter the urinary tract.

I hope this helps
