Large Y-shaped protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. These antibodies are produced by plasma B cells which are found in circulation, but are primarily in lymph nodes.
system of biological structures and processes within an organism that protects against disease. to function properly the immune system must detect a wide variety of agents and then distinguish them from the organisms own healthy tissue.
1st defense: skin,sweat,mucus, and tears.protector of viruses and bacteria
Cells that protect the body by ingesting harmful foreign particles,bacteria, and dead or dying cells. they are essential for fighting infections nd for subsequent immunity. highly developed within vertebrates
Viruses,fungus,bacterium,prion are all microorganisms that cause disease
Was the pathogen bacterial or viral?How does the body attempt to fight invading pathogen? How does your immune system recognize the pathogen?
the pathogen was bacterial.Your body fights off pathogens by using its defenses(1st and 2nd line) if the pathogen passes the first line the second line comes inand ingest the pathogen to produce antibodies. Your immune system recognizes a pathogen because the antibodies present in our body will bound to the antigen specifically with the complementary and exhibit immune response
