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.

Which are specific molecules that are recognized by the body as foreign and to which antibodies bind known as?
Specific molecules that are recognized by the body as foreign and to which antibodies bind are called antigens. Antigens can be proteins, carbohydrates, lipids, or nucleic acids that stimulate an immune response when they enter the body.
Antibodies are produced when the body is exposed to?
soluble antigens whch entrs our body
How do antigens protect the body from diseases?
Antigens do not protect the body from disease. Antibodies protect the body from many diseases.
Pathogens that enter the body are?
When pathogens enter the body, they begin to cause disease. Path=disease+ gen=to make (or generate).
Substances or organisms that are foreign to the body?
Antigens is the term for molecules that are foreign to the body.
What is the name of foreign molecules in the body?
Foreign molecules in the body are often referred to as antigens. These antigens can trigger an immune response from the body's immune system to defend against potential threats.
What is the reason why the body need millions of antibodies for detecting millions of antigens?
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,
Substances that the body recognizes as foreign are called?
Substances that the body recognizes as foreign are called antigens. Antigens can be proteins, carbohydrates, or any other molecule that triggers an immune response by the body's immune system.
What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.
How does a B cell tell the difference between an invader cell and a body cell?
B cells recognize invaders by binding to specific antigens on their surface that are not present on body cells. If a B cell encounters an invader with matching antigens, it will be activated to produce antibodies against the invader, while sparing body cells that do not display those antigens.
What is the foreign material that invades the body?
antigens
What are Foreign substances in the body known as?
antigens
