Guida verificata passo dopo passo1
Understand that the human immune system is composed of multiple layers of defense mechanisms against pathogens.
Recognize that the first line of defense is a physical and chemical barrier that prevents pathogens from entering the body.
Identify the components of this first line of defense, which include the skin and mucous membranes.
The skin acts as a physical barrier, preventing the entry of pathogens, while mucous membranes line body cavities and secrete mucus to trap and expel invaders.
Differentiate this first line of defense from other immune responses such as the inflammatory response, adaptive immunity, humoral response, and cell-mediated response, which are part of the body's second and third lines of defense.
