They can enter the body in various ways. Mouth, nose, skin, ear, eyes, etc. Any entry way for bacteria is an entry way for disease- causing agents. Hand contact with someone who has those agents can cause one to
Once contact occurs, disease-causing agents, such as viruses and bacteria, may enter a person through breaks in the skin, or they may be inhaled or swallowed. Others may enter the body through the moist linings of the eyes, ears, nose, mouth, or other body openings.

The immune system produces antibodies to defend against allergens.
Asthma does not enter your body, its something you develop along with an allergy to something, or it can come with cold weather and constricts your lungs. As well, excercise can trigger an asthmatic espisode. You can be born with it, or develop it.
No an allergen can enter the body by breathing it in. This will cause an asthma attack.
Cats and horses, dust, tobacco are a few of my triggers, cats get me right away, my eyes get affected too. Red, swollen and itchy, feels terrible.
Hope this is somewhat helpful
They occur when your body detects a non-harmful substance as harmful. Your body then sends histamines to the site, which inflames the area and coats the allergens with secretions. These help escort the allergens out and if they are unable to do so, the body isolates them.
Allergens enter the body through four main routes: the airways, the skin, the gastrointestinal tract, and the circulatory system
soluble antigens whch entrs our body
Antigens do not protect the body from disease. Antibodies protect the body from many diseases.
When pathogens enter the body, they begin to cause disease. Path=disease+ gen=to make (or generate).
Antigens is the term for molecules that are foreign to the body.
Processed fragments of protein antigens displayed on surfaces of body cells.
antibodies are need to protect body from haremfull substanse, and millions are need because every antigen which enter our body have difefrent shape and characterestic,
A foreign material that invades the body is called an antigen. Examples of antigens are bacteria, dust particles, viruses and toxins.

An "antigen" is a substance that when introduced into the body stimulates the production of an "antibody".Antigens include toxins, pollen, bacteria, viruses, metals, foreign blood cells and the cells of transplanted organs.A "disease" is a pathological condition of some part of an organ or living system resulting from various causes.Diseases include infections, genetic defects, or environmental stresses and are characterized by an identifiable group of signs or symptoms.Thus you can see some diseases are caused by antigens and some diseases that are not caused by antigens.
