The immune system’s three lines of defense include physical and chemical barriers, nonspecific innate responses, and specific adaptive responses.
What is the 1st, 2nd and 3rd line of defense?
In the three lines of defense model, management control is the first line of defense in risk management, the various risk control and visibility compliance functions established by management are the second line of defense, and independent assurance is the third.
Which 3 body systems are the first line of defense?
Skin, tears and mucus are part of the first line of defense against infection. They protect us from invading pathogens.
What are the 3 levels of the immune system?
What are the three lines of defense? Chemicals in saliva, tears, mucous membranes, etc. You’ve just finished 13 semesters!
What are the 3 lines of defense of the immune system?
The immune system’s three lines of defense include physical and chemical barriers, nonspecific innate responses, and specific adaptive responses.
What is the second line of defense?
The second line of defense is nonspecific resistance, which destroys invaders in a general way without targeting specific individuals: phagocytes ingest and destroy any microbes that invade body tissues. For example, macrophages are cells derived from monocytes (a type of white blood cell).
What does the third line of defense include?
The third line of defense is called the immune response and is SPECIFIC. It involves the production of two types of lymphocytes (B and T cells) specific to the invading particle. They work together to attack the pathogen.
What are the body’s first three lines of defense?
The human body has three main lines of defense to ward off foreign invaders including viruses, bacteria and fungi. The immune system’s three lines of defense include physical and chemical barriers, nonspecific innate responses, and specific adaptive responses.
What is the body’s first line of defense?
The first line of defense is your innate immune system. The first level of this system consists of physical barriers such as your skin and the lining of your airways. Tears, sweat, saliva and mucus produced by the skin and mucous membranes are also part of this physical barrier.
What are the 1st, 2nd and 3rd lines of defense of the immune system?
The second line of defense are the nonspecific phagocytes and other internal mechanisms that make up innate immunity. The third line of defense are specific lymphocytes that produce antibodies as part of the adaptive immune response.

What are the three levels of immunity?
The cellular immune response has three phases: cognitive, activation and effector.
