The body's three lines of defense against a pathogen (germ) are:
1. Anatomical and physiological barriers-Includes skin, hair, mucous membranes, saliva, tears, stomach acid, pH, temperature.
2. Non-specific response-Includes phagocytosis of pathogen, inflammation of tissues, vasodilation (increased blood flow to area), and swelling.
3. Specific response-antibody production and cell mediated immunity to particular pathogen. Maintained indefinitely.
The first line of defense, which includes physical barriers like skin and mucous membranes, acts as a physical and chemical barrier to prevent pathogens from entering the body. These barriers provide a primary defense by blocking the entry of pathogens, trapping them in mucus, and preventing straightforward access to the internal environment where they could cause harm.

True or false The skin provides the first defense against invasion by pathogens?
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 first line of defense during a phlebotomy procedure?
The first line of defense during a phlebotomy procedure is strict adherence to aseptic technique, which involves thorough handwashing and the use of gloves. This helps prevent the introduction of pathogens into the bloodstream.
When does the bodys second line of defense come into play?
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.
What is the main line of defense?
The main line of defense in the human body is the immune system, which helps to protect against pathogens such as bacteria, viruses, and parasites. This includes physical barriers like the skin, as well as specialized cells and proteins that work together to identify and neutralize harmful invaders.
What is the first line of Mitch's non-specific defenses?
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.
What is a fact about the integumentary system?
It is the first line of defense against pathogens.
What organ provides the first line of defense against infection?
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.
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.
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.
True or false The skin provides the first defense against invasion by pathogens?
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.
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.
What is the bodys first defense against bacteria and viruses?
Lysozymes
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.
The first line of defense during a phlebotomy procedure?
The first line of defense during a phlebotomy procedure is strict adherence to aseptic technique, which involves thorough handwashing and the use of gloves. This helps prevent the introduction of pathogens into the bloodstream.
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.
When does the bodys second line of defense come into play?
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.
