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.

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
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.
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.
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.
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.
