Explanation:
what differences between physical and chemical barriers
Answer:
Mechanical barriers — which include the skin , mucous membranes , and fluids such as tears and urine — physically block pathogens from entering the body. Chemical barriers — such as enzymes in sweat , saliva , and semen — kill pathogens on body surfaces.
Physical barriers and chemical barriers are two types of barriers in the immune system. These barriers help prevent the entry of pathogens into the body. There are differences between physical and chemical barriers.
Physical barriers are physical structures that prevent the entry of pathogens into the body. These barriers include the skin, mucous membranes, and cilia. The skin is the most significant physical barrier. It covers the entire body and serves as a barrier against pathogens. The skin has a few layers that prevent the entry of microbes.
Additionally, the skin has sebaceous and sweat glands that produce sebum and sweat, respectively. These secretions have antimicrobial properties. Mucous membranes are another physical barrier. They line various parts of the body, such as the respiratory tract, gastrointestinal tract, and reproductive system.
They secrete mucus, which traps microbes and foreign particles. Cilia are hair-like structures that line the respiratory tract. They move in a coordinated manner and help remove microbes from the respiratory tract.
