What are 2 examples of the second line of defense?
13.2: Second Line Defenses: Cells and Fluids
- Neutrophils (PMNs)
- Eosinophils.
- Basophils.
- Mast Cells.
What are the second line of defense mechanisms?
If pathogens are able to get past the first line of defence, for example, through a cut in your skin, an infection develops. The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
What is the second line of defense quizlet?
Second Line of Defense actions include: recognition, inflammation, fever, phagocytosis, interferons, and complement.
What is the second line of defense in innate immunity?
The second line of defense against non-self pathogens is called adaptive immune response. Adaptive immunity is also referred to as acquired immunity or specific immunity and is only found in vertebrates.
Which is a secondary line of defense against infections quizlet?
white blood cells (leukocytes) which engulf pathogens by extending pseudopods to surround it.
Which of the following is a second line of defense quizlet?
The second line of defense are internal defenses such as phagocytes, natural killer cells, inflammation, fever, and antimicrobial proteins.
Which of the following terms are components of the second line of defense?
The second line of defense are the non-specific phagocytes and other internal mechanisms that comprise innate immunity. The third line of defense are the specific lymphocytes that produce antibodies as part of the adaptive immune response.
What is non specific defense?
Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN. Specific defenses include antibody (more…) Although interferon was first recognized as an extraordinarily potent antiviral agent, it was found subsequently to affect other vital cell and body functions.
What are nonspecific mechanisms?
Nonspecific defense mechanisms include the skin, mucous membranes, secretions, excretions, enzymes, inflammatory responses, genetic factors, hormonal responses, nutritional status, behavior patterns, and the presence of other diseases.
What are examples of nonspecific defenses?
NON SPECIFIC DEFENSES: Skin and Mucous membranes, antimicrobial chemicals, natural killer cells, phagocytosis, inflammation and fever.
What is nonspecific Defence?
Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. These barriers are aided by various antimicrobial chemicals in tissue and fluids.
What is the body’s second line of defense when does it take effect?
When does it take effect? -The body’s second line of defense includes the inflammatory response and phagocytosis by nonspecific leukocytes. The defense attacks pathogens that manage to enter the body. It takes effect after the first part fails.
What line of defense is nonspecific?
First line of defense The body’s most important nonspecific defense is the skin, which acts as a physical barrier to keep pathogens out. Even openings in the skin (such as the mouth and eyes) are protected by saliva, mucus, and tears, which contain an enzyme that breaks down bacterial cell walls.
What are the first and second lines of Defence?
The first line of defense against infection are the surface barriers that prevent the entry of pathogens into the body. The second line of defense are the non-specific phagocytes and other internal mechanisms that comprise innate immunity.
