The two major functions of the immune system is to prevent illnesses/diseases from coming and destroying one's body and also to keep your body strong and not get illnesses.
fight against illnesses
The immune system is a network of cells tissues organs and chemicals that fight pathogens. This is how the body keeps healthy and defends against invading illnesses.
when a person is born with an immune system that doesn't function, the body is unable to fight and survive infections by pathogens that don't cause any problems for a robust immune system.
The immune system is the body's defense system that helps fight off bacteria and viruses. It is made up of a network of cells, tissues, and organs that work together to protect the body from harmful pathogens.
The function of the immune system is to protect your body from infection by pathogens and foreign invaders, or what the body perceives as invading "germs". Your immune system works to identify pathogens and sometimes other unrecognized cells, like tumor cells, that could cause disease and then to eliminate them from your system. Your body's immune system has an incredibly difficult task in this because some of these pathogens can be "sneaky": they can redesign (mutate) themselves to trick the immune system into misidentifying them as harmless cells rather than appropriately treating them as foreign invaders.
Ann antibody is a complex protein molecule. Our immune system uses antibodies to fight bacteria.
Because it has a lot of very varied jobs to do, and many different pathogens to fight against.
Antibodies are important for the immune system's defense against pathogens because they specifically target and neutralize harmful invaders like bacteria and viruses, helping the body to fight off infections and stay healthy.
White blood cells help to defend against pathogens by: ■ ingesting pathogens ■ producing antibodies, which destroy particular bacteria or viruses ■ producing antitoxins, which counteract the toxins released by the pathogens.
The Immune System
The body's first line of defense is the innate immune system, which includes physical and chemical barriers like skin, mucous membranes, and stomach acid that help prevent pathogens from entering the body. If pathogens breach these barriers, the immune system responds with inflammation and activates other immune cells to fight off the infection.
Antibodies, also known as immunoglobulins, are proteins produced by plasma cells in the immune system to target and neutralize infectious agents such as bacteria, viruses, and other pathogens. These antibodies bind to specific antigens on the surface of the pathogens, marking them for destruction by other immune cells.
