Immune System

Antigen

No, the immune system is not an organ. It is a system in your body that fights of viruses that enter your body. And example of an organ is a heart, or liver. The immune system are cells that fight off viruses that can make you sick.

mucous membranes of the respiratory tract

The first defense is nonspecific.

They all can be, but not all bacteria ec cause disease and some are symbiotes.

Antigen

A tree....the air instead of soil...the roots are the nose, mouth and throat and glottis...the trunk and branches are the bronchi and bronchioles.....the alveoli are the leaves,,,the bloodstream is the air exchanging oxygen and carbon dioxide.

It can build up white blood cells to fight against the infection and if it is present again you will all ready be immune to it. That is why vaccinations have a small amount of the infection in them, so you can become immune to it later.

Epidermal cells that aid in the immune response include melanocytes.

Well, lets start with the basics, your immune system is what keeps you from getting colds and flu's easily.

so your auto-immune system (protection) automatically defends your body against these types of attacks, where anti-immune are the things trying to attack your immune system (Virus).

Yes and no. Your immune system is constantly at work, keeping your body temperature regulated and fighting average germs that attack you everyday (including the ones that sneak into your body when you rub your eyes with your hand or when you pick your teeth with a fingernail) and you can't really feel it working then, but you can feel and see the products of its work. For example, puss in a wound is the result of the immune system working to fight bacteria and infection in and around the injury. Also, when you blow your nose during a cold, the thicker, darker mucus that your mom and dad or your doctor says is a good thing is the result of your immune system working hard to get rid of the germs that are getting and keeping you sick. Another sign that your immune system is working is what is called a fever break. A fever break is the result of your body's immune system working extra hard to fight bacteria and because of that hard work, it uses lots of energy, which heats up your body.

The EPI or expanded program of immunization by the DOH is a program developed by the DOH in the Philippines that mandates the Filipino children to be immunizad against the immunizable disease known. This includes the BCG vaccines, Hepa B vaccine, OPV, DPT vaccine, and the Measles vaccine. All of which have different intervals and dosages that should be given to the child before reaching 1 year old.

this kind of question how i know to answering but i have a opinion. firstly just back home and sleep

Absolutely not. Leukemia is a form of blood or bone marrow cancer and is not transmitted through needles, sex or any other methods, unlike AIDS and HIV. I know because my loving husband has lived with it bravely for years.

IF .. they're trapped in the mucous of the upper airways, then you either sneeze (or cough) them out or you swallow them (and digest them in your stomach).

Otherwise you must depend on antibodies and white cells to do their job.

it is decrease in leucocyte count in blood

Both are T and B lymphocytes are produced in bone marrow, but B lymphocytes mature in bone marrow and are part of the humoral response, while T lymphocytes mature in the thymus gland and are part of the cell mediated response.

The radiation kills bone marrow, where both red and white blood cells are made. The white blood cells produce most of the immune system, with fewer white blood cells the immune system weakens.

immunology

vaccines contain either live or killed antigen .live vaccines contain attenuated (weakened)viruses which do not have the ability to cause disease.when the vaccine is injected the body produces anti-bodies against it .next time when the virus enters by that time the body has enough anti-bodies to fight the disease causing virus successfully.

Leukocytes are white blood cells

Echinacea is reported to have a beneficial effect on the immune system. It is said to help to both prevent colds as well as shorten the duration of a cold if taken at the first sign of symptoms. While it hasn't been substantially against colds, it has been proven to provide a boost to the immune system.

it is the white blood cells

The measles virus is transmitted via respiratory secretion and causes very serious illness. It first infects the conjunctiva, respiratory tract urinary tract and the central nervous system.

Viral pathogens cause colds, flu, and chickenpox.
