Describe how anatomical barriers and mechanical removal are important in preventing infections?

Answer 1

The first line of defense in any immune system is the integument (or skin) - an anatomical barrier. This prevents the pathogens from getting into the body, instead of having to remove them or kill them once they're in the body.
An example of mechanical removal is in the lungs. There are special cells which produce mucus. It is very sticky, so many pathogens, and other particulate matter in the air (that is not good for the lungs) gets caught in it. Then, there are other cilliated cells, which beat in a direction so that the mucus (with material caught in it) is moved up the airways into the oral or nasal cavity, where it can be expelled.

Answer 3

anotomical barriers are our natural God-given protection from infection. these includes the skin, the fluids, the blood, the hairs found all over the inside and outside of our body. Mechanical removal is also essential to help aid the body in recovering from infection. It helps by preventing the bacteria from multiplying, hence it is needed in case the body is weak in defending himself
