Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

How can you get your nails to grow faster naturally?
you can't really. If your nail are damaged they won't grow as fast as you want them to. look after your health and take care of your nails.
Permanent immunity happens when someone is immune to a disease because they have already been exposed. The body remembers the disease from the first attack, and will generally fight it off before you get sick.
How does the skin and mucous membranes help prevent infection by a pathogen?
The physical and chemical factors that provide protection from disease in the skin and mucous membranes are the many layers of closely packed, keratinized cells, in the epidermis that provides a formidable physical barrier to the entrance of microbes. The epithelial layer of mucous membranes secret a fluid called mucus that is sticky and traps microbes and foreign substances. The lacrimal apparatus produces and drains away tears in response to irritants, diluting microbes and keep them from setting on the surface of the eyes. Sebaceous glands of the skin secrete an oil substance called sebum that forms a protective film over the surface of the skin. Perspiration helps flush microbes from the surface of the skin and contains lysozyme, an enzyme capable of breaking down the cell walls of certain bacteria.
What are substances made in response to a specific antigen?
Giant turtles are what are made in response to a specific antigen. Hope I Helped!
acquired immunodeficiency syndrome
Why does a vaccine have to be a specially prepared version of a disease pathogen?
A vaccine is a special version of an antigen the gives you immunity against a disease. A vaccine is a weakened form of disease which helps your immune system create antibodies to fight it off so later if you ever get that certain disease again your body would recognize it and create antibodies to fight against it before it gets too serious.
What is term for disease where the immune system attacks the person's healthy tissue?
There are several, the most well-known one probably AIDS.
Is the integumentary the same thing as the immune system?
no it is not. The integumentary system is your skin, hair, nails, and sweat/oil glands. It works with the immune system in that it helps protect the body. The immune system helps fight off bacterial infections and viruses on the inside. they work together, but they are not the same thing.
How does continuous and prolonged stress affect the immune system?
Very simply stated: Stress causes an increase in the hormone cortisol. Cortisol is a glucocorticoid steroid and has a supressive effect on the immune system, as do all glucocorticoid steroids (ex. dexamethasone). They suppress the inflammatory process which is critical in a properly functioning immune system.
The ways in which the immune system is suppressed by glucocorticoids is EXTREMELY complex, but a simple way to put it is that it keeps white blood cells from doing their job and keeps them from communicating with other white blood cells.
What is a voice response system?
i'm almost positive it's when a machine can sense someone's voice. for example, when you say to your car "call Mikey" and then it calls Mikey.
:)
Can you explain and give a list of different pathogenic organisms?
An organism of microscopic size, usually a bacteria or virus, that causes disease.
(bacteria, fungi, parasites, and viruses)

Are the nails on your toes made out of the same material as the nails on your finger?
Yes, both fingernails and toenails are made of a protein called keratin, which is also the main protein found in human hair.
The part of the nail that you can see is actually non-living tissue. The only living part of the nail is the matrix, most of which lies hidden beneath the skin at the base of the nail, just as the only living part of a hair is the root hidden beheath the skin.
Do spicy foods help immune system?
Yes, it will.
A balanced diet contains carbohydrate, protein, fat, vitamins, mineral salts and fibre. It must contain these things in the correct proportions.
Carbohydrates: a source of energy.Proteins: a source for growth and repair.
Fats: a source of energy and contain vitamins too.
Vitamins: A B C D E; essential for metabolic reactions.
Mineral Salts: required for healthy teeth, bones, muscles etc..
Fibre: helps intestines function correctly.
Exercise is a best way to boost your immune system.
JUNK food; chips and coke sucks you!!! Avoid them.
Enjoy.
What are monokines and lymphokines?
There is a general term called cytokines. These are secreted molecules with autocrine (self taget), paracrine (local target), and endocrine (far target) functions. These chemicals can be used to alter behavior of a cell (vasoactivate endothelial cells to leak out plasma), commit a cell to apoptosis (cytotoxic), or attract cells form the adaptive and innate immune system to perform a function (chemotaxis). Lymphokines are a subclass of cytokines which are released by cells of the lymphoid progenitor (b-cells, t-cells, and NK cells). Monokines are a subclass of cytokines which are sercreted by monocytes and macropohages. Macrophages are mature Monocytes which are made from a myeloid progenitor.
What virus attacks the cells in the immune system that produce antibodies-?
Not sure if it's a disease or virus (I'm tired), it's HIV and gives you AIDS. AIDS attack the T Cells that produce antibodies, which makes you vulnerable to sickness. You can get it from (no offense) gay s*x (for the children) and by injecting drugs into yourself I think. There may be another way, but I don't remember.
Why are your monocytes and eosinophils high?
Most likely there will be some type of inflammation present. Typically an allergy or infection. They release histamine and have anticoagulant heparin to help contribute to the inflammation process and promote blood flow to the affected area.
(Basophils are white blood cells involved in the body's immune system)
What is the contraindications for G6PD?
Mothballs can kill someone with G6PD Deficiency in a matter of a few hours. As far as food goes... anything with soy in it, and any products made from soy (which there are many). ALL legumes (beans, peas, peanuts, etc.) are also contraindicated. Drugs... there are too many to list. The most complete database of drugs or food is at g6pdeficiency.org. You can type in any food or drug and find out what the contraindications are. You can also join the forum (for free of course) and ask any question you want. The forum members are knowledgeable and experienced on the most recent info regarding all aspects of G6PD. As evidenced by the comments in the forum, from people who have G6PDD, or who have lost friends and loved ones because of it, there is a lot of mis-information floating around the net, and in the medical world. People are sick and dying unnecessarily because of lack of accurate information about this enzymopathy.
What consists of pathogens that have been weakened?
Live vaccines contains weakened viruses of the disease. These viruses can not cause the disease but give immunity to the recipient. ( In the initial days of such trials, 18 patient got the rabies due to vaccine and died.)
