There are several ways to interpret the question. For some, the first line of defence is the skin since it acts as an impermeable barrier and also has antibacterial properties due to the acids secreted and normal bacteria fauna on the skin. However, since most pathogens, being capable of causing disease, can inherently overcome the skin defense, the first line of immune defence is the innate immune system that exists in the tissues underlying epithelia (skin or any mucous membranes). The innate immune system has cells that can recognize and destroy pathogens without specificity.
True. The skin acts as a physical barrier and provides the first line of defense against invasion by pathogens, preventing them from entering the body.
The body's second line of defense, which includes inflammatory responses and phagocytic cells, comes into play when pathogens manage to breach the first line of defense (skin and mucous membranes). These responses help contain and eliminate the pathogens before they can cause harm.
The first line of Mitch's non-specific defenses is the physical barriers provided by the skin and mucous membranes. These barriers serve as the body's first line of defense against pathogens by preventing their entry into the body.
The first line of defense against disease is the body's innate immune system, which includes physical barriers like the skin and mucous membranes, as well as specialized cells that target and destroy pathogens. These defenses work to prevent pathogens from entering the body or to eliminate them quickly before they can cause harm.
Your skin is the first line of defense.
It is the first line of defense against pathogens.
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
True. The skin acts as a physical barrier and provides the first line of defense against invasion by pathogens, preventing them from entering the body.

Lysozymes
The integumentary system is one of the first lines of defense against infection. It provides a physical and chemical barrier against the entry of pathogens.
Your skin is the first line of defense against pathogens that try to enter the body.
The body's second line of defense, which includes inflammatory responses and phagocytic cells, comes into play when pathogens manage to breach the first line of defense (skin and mucous membranes). These responses help contain and eliminate the pathogens before they can cause harm.
skin and mucous membranes
The skin acts as the first line of defense against infection by creating a physical barrier to pathogens. It contains antimicrobial peptides and sebaceous glands that help protect against harmful microorganisms.
