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.

What are your bodys first line defenses against pathogens in general?
Your skin is the first line of defense.
When does the bodys second line of defense come into play?
when it gets past the first line (the skin)
How does the body's first line of defense function?
The Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defenses act the same way to all pathogens, in which they're called non-specific defense.
What is the body first line of defense against bacteria and viruses?
saliva, mucus, hairs and Skin
What is a fact about the integumentary system?
It is the first line of defense against pathogens.
What organ is your 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.
What are your body's first-line defenses against pathogens in general?
Your skin is the first line of defense.
What are your body' first-line defenses against pathogens in general?
Your skin is the first line of defense.
True or false The skin provides the first defense against invasion by pathogens?
True
Is the integumentary system the second and third line of defense against infection?
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.
What are your bodys first line defenses against pathogens in general?
Your skin is the first line of defense.
When does the bodys second line of defense come into play?
when it gets past the first line (the skin)
Why is the skin consider part of the immune system?
Your skin is the first line of defense against pathogens that try to enter the body.
Which of these is the human body's first line of defense against invading pathogens such as bacteria and viruses?
skin and mucous membranes
Is the stratum spinosum the first line of defense?
No, the stratum corneum is the first line of defense in the skin against pathogens. It consists of a layer of dead keratinized cells that provide waterproofing and protect underlying layers of skin.
Is skin the first line of defense against the invasion of pathogens?
a diseas that can be passed from one living thing to another is an infectious disease
