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.

What else can I help you with?
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.
When antigens enters the body?
When antigens enter the body, they are recognized by the immune system as foreign substances. This triggers an immune response, where specialized cells like T cells and B cells are activated. B cells produce antibodies that specifically target the antigens, while T cells help coordinate the immune response and directly attack infected cells. This process helps the body to neutralize or eliminate the invading pathogens.
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?
Antigens Antibodies neutralize these molecules.
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?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
What are produced when the body is exposed to antigens?
Antibodies.
