How do T cells and B cells of your immune system respond to pathogens?

T cells's
primary task is to activate B cells and killer T cells. The B cells
searchfor antigens matching its receptors. If it finds such antigen it connects to it, and inside the B cell a triggering signal is set off.

What happens when the body cannot differentiate between pathogens and body cells?
The immune system will target the body's own cells
What helps the immune system?
The system that helps the immune system is the circulatory system because it carries the white blood cells to where the pathogens are.
Which are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells?
Antibodies are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells.
What is a network of cells tissues organs and chemicals that fight pathogens?
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.
What are response cells?
Response cells are cells that respond to the immune system and react to diseases.
What is the function of the immune system?
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.
Which cells in the immune system identify pathogens and distinguish one pathogen form another?
T cells
What is a network of cells tissues organs and chemicals that fights off pathogens?
immune system
Which cells in the immune system identify pathogens and distinguish one pathogen from another?
B cells and Helper T cells
How does the immune system function and protect against pathogens?
The immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens such as bacteria, viruses, fungi, and parasites. Its primary function is to recognize and eliminate these pathogens while distinguishing them from the body's own healthy cells. The immune system can be broadly divided into two main components: the innate immune system and the adaptive immune system. Innate immune system: This is the first line of defense and provides a rapid, nonspecific response to pathogens. It includes physical barriers like the skin and mucous membranes, as well as various cellular and chemical components. The innate immune system recognizes certain patterns associated with pathogens, called pathogen-associated molecular patterns (PAMPs), through receptors on immune cells. These cells include phagocytes (such as macrophages and neutrophils) that engulf and destroy pathogens, natural killer cells that kill infected cells, and dendritic cells that present antigens to initiate an adaptive immune response. The innate immune system also releases chemical signals called cytokines that help coordinate the immune response. Adaptive immune system: This is a specific and highly specialized defense mechanism that develops more slowly but provides long-term protection against specific pathogens. The adaptive immune system has the remarkable ability to recognize and remember specific pathogens it has encountered before. It involves two main types of cells: B cells and T cells. B cells: B cells produce antibodies, which are proteins that bind to specific molecules on pathogens called antigens. When an antigen is encountered, B cells undergo activation and differentiation into plasma cells that produce large quantities of antibodies. Antibodies can neutralize pathogens directly, mark them for destruction by other immune cells, or activate the complement system, which is a group of proteins that help eliminate pathogens. T cells: T cells have several roles in the immune response. Helper T cells recognize antigens presented by dendritic cells and help coordinate the immune response by releasing cytokines. Cytotoxic T cells, also known as killer T cells, directly destroy infected cells by releasing toxic substances. Regulatory T cells modulate the immune response to prevent excessive reactions and maintain tolerance to self-antigens. Both the innate and adaptive immune systems work together in a coordinated manner. When a pathogen breaches the physical barriers of the body, innate immune cells detect its presence and initiate a response. This response activates the adaptive immune system, which mounts a targeted attack against the specific pathogen. After the infection is cleared, some adaptive immune cells remain as memory cells, providing long-lasting immunity. If the same pathogen is encountered again, the immune system can mount a quicker and more effective response, preventing reinfection. It's important to note that the immune system is a highly intricate and dynamic system, and its functioning can be influenced by various factors such as genetics, overall health, nutrition, and previous exposure to pathogens.
When the immune system does not respond to a particular antigen?
Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.
How does your body kill pathogens that get inside us?
Your body's immune system goes up in temp. The result is killing them
