What are the 7 nonspecific defenses?

What are the 7 nonspecific defenses?

Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN.

What are the nonspecific immune defenses?

Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response.

What are nonspecific and specific defenses?

Nonspecific protective mechanisms repel all microorganisms equally, while the specific immune responses are tailored to particular types of invaders. Both systems work together to thwart organisms from entering and proliferating within the body.

How do nonspecific defenses protect the body?

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 is the body’s most important nonspecific defense?

The Body’s MOST IMPORTANT Nonspecific Defense is the SKIN. UNBROKEN Skin provides a continuous layer that protects almost the whole body. Very Few Pathogens can penetrate the layers of dead cells at the skin’s surface.

What are the specific defenses and how do they defend the body?

Natural barriers and the immune system defend the body against organisms that can cause infection. (See also Lines of Defense.) Natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid. Also, the normal flow of urine washes out microorganisms that enter the urinary tract.

How do specific defenses work?

Specific defense: the adaptive immune system. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen.

What are specific body defenses?

Specific Defense. Specific defense (sometimes called adaptive immunity) recognizes and coordinates attacks against specific pathogens. The system can also remember pathogens and produce a powerful response the next time a pathogen enters the body.

What is the body’s nonspecific defense against invading pathogens?

What are the body’s three defenses?

The human body has three primary lines of defense to fight against foreign invaders, including viruses, bacteria, and fungi. The immune system’s three lines of defense include physical and chemical barriers, non-specific innate responses, and specific adaptive responses.
