Answer 2

• Skin contains tightly packed cells.

• Skin is tough, flexible, and waterproof.

• You cough when a pathogen enters your mouth.

• You sneeze when a pathogen enters your nose.

Step-by-step explanation:

The physical barriers of the immune system prevent infections since they stop or expel any pathogen that enters the body. The skin with its cells tightly packed and characteristics, the endothelia, and mucous membrane, like the one in our nose, are physical barriers. They stop antigens from infecting our body since they can remove them by sneezing, coughing, or shedding.
