Non-specific defenses in your body guard you against many harmful substances. This includes the skin and mucous membranes, cellular and chemical factors, microbial antagonism, transferrin, fever, interferons, the complement system, acute-phase proteins, cytokines, inflammation, and phagocytosis.
If you need further explanation of any of these individual parts, please contact me on my page.
Innate Defenses:
Ones we are born with these. All invaders are dealt with using a limited array of weapons. They can not be modified to enhance the response. These have been called non-specific defenses since any invasion triggers it. Splinters, burns, cuts, blows, etc. It is not one-one response.
Inflammation is a coordinated response that involves innate defenses. Redness, heat, pain, and swelling.
Fever acts to discourage infection.
Physical barriers include the skin and mucous membranes of the respiratory tract, GI tract, urinary tract and genital tract. The flow of product on the membrane removes pathogens.
Antimicrobial substances such as lysozymes, peroxidase enzymes, lactoferrin, and defensins inhibit or kill microorganisms.
Normal Flora competes with pathogens for the same niche and stimulates the host defenses. Protection is very important. These prevents adherence. Disruption of the normal flora can result in various infections by opportunists.
the skin
These are non-specific (splinters, cuts, bruises) not one on one responses:
1. Physical barriers include the skin and mucous membranes of the respiratory tract, GI tract, urinary tract and genital tract. The flow of product on the membrane removes pathogens.
2. Antimicrobial substances such as lysozymes, peroxidase enzymes, lactoferrin, and defensins inhibit or kill microorganisms.
3. Normal Flora competes with pathogens for the same niche and stimulates the host defenses. Protect is very important. These prevents adherence. Disruption of the normal flora can result in various infections by opportunists.

Interferons, transferrin and complement proteins. Anatomic and physiologic barriers
defence is the correct English way of spelling it. DEFENSE is the American IN correct way of spelling it.
Nonspecific defenses against diseases include intact skin, fevers, nonspecific phagocytes such as neutrophils and macrophages.
true
Lysozymes
1- skin 2- WBCs present in the blood 3- even fever and inflammations can be considered as defences 4- production of immunoglobulins 5- HCL acid produced by the stomach and there are too many others defences that can be studied in each organ or biological system specifically
Immunodeficiency is the inability of a body to fight infection because of the lack of the T-cells.
"Immunological system" is just a fancy way to say "immune system".
Non specific defenses against pathogens include intact skin, temperature, neutophils, macrophages, and natural kills cells.
Neutrophils
Your skin is the first line of defense.
true
when it gets past the first line (the skin)
through the digestive system.
The tonsils are apart of the lymphatic system. They aid in the bodys ability to fight germs.
Inflammation is one of the bodies non-specific defenses. It helps localize the infection to stop it from spreading to other areas of the body so that your bodys other defenses can come in and fight the infection.
White blood cells
how do vaccines help the bodys natural defences against viruses ??
The disease is cancer
