Macrophages ( in the lymph nodes ) act like phagocytes to engulf and digest the pathogen. But they do not fully digest it. They separate out the antigens and incorporate them into a cell surface molecule. This is exposed on the surface of the macrophage, which becomes known as an antigen-presenting cell. Its function is to find the lymphocytes that can neutralise that particular antigen.

What do lingual tonsils inhibit?
Antigens and bacteria
What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
Do all bacteria have antigens if so what would happen if it entered your system?
yes they do
How is invading bacteria detroyed?
The bacteria has tiny, oddly-shaped molecules on it's surface, which are different for every type of bacteria, these are called antigens. When a special type of white blood cell, called a lymphocyte, realises an invading bacteria is in the bloodstream, it starts to make tiny connectors called antibodies. These antibodies fit the antigens on the bacteria's surface, and join many bacteria together. Once lots of bacteria have been joined together, another type of white blood cell, called a phagocyte, engulfs them, and it will usually take a few days for all the bacteria to be destroyed.
What are molecules on the outer surface of a cell that identify it as long friend or for?
Antigens- Each human being has his or her own unique cell surface antigens, as do to all other living things, including bacteria, virus, animals, and plants.
What is the job of white blood cell?
To produce antibodies, engulf antigens and produce antitoxin. They do this to protect the body of disease-causing bacteria and viruses.
What is the use of genetically engineered bacteria?
The can produce antigens useful in making vaccines without the harmful parts of the original disease organism.
Antigen and antibody?
An antigen is a foreign particle that enters the body. This could be a disease causing agent such as part of a bacterium or virus or could be a particle such as pollen or dust. An antibody is a protein made by the body's immune system. Antibodies react with specific antigens to enable the antigens to be removed from the body.
Bacteria and debris are actively removed from the lymph by?
Macrophages
What can prevent us from getting sick from antigens and bacteria?
Fill a glass with 1/3 cup of oil and 1/3 cup of vinegar. Drop in four quarters, fresh off the mint, and let sit for seven days. Take off your shoes and soak your middle toe in this liquid for three hours. Bacteria and Antigens will never bother you again.
Does Type B blood have A antigens?
No, type B blood does not have A antigens. Type B blood has B antigens.
