A macrophage cell capturing bacteria. C. staphylococci Usually, dendritic cells will ingest and destroy cancerous cells and display their proteins on their cell surfaces to initiate a wider immune response, drawing in other immune cells to respond to the threat, helping them to better recognize and target the harmful cancer cells. Also, inflammation--an attempt to provide more cells to repair damage--can end up causing more damage, such as with meningitis. Dendritic cells have projections that extend from the body of the cell that are similar in appearance to the dendrites of neurons. A disease-causing organism, including bacteria, Molecule that stimulates an immune response, Specialized Y-shaped protein that tags antigens for destruction, White blood cells that produce antibodies and aid in immunological memory, White blood cells specialized to assist B cells (helper T) and others directly kills infected cells (killer T), Adaptive immune defense depending on the action of antibodies, Adaptive immune defense in which foreign cells are destroyed by T cells, Nonliving particle containing protein and DNA/RNA that can infect a living cell, A killed or weakened form of a pathogen that produces immunity when injected into the body. white blood cells rhat specialize so they can attack specific microorganisms. When NK cells come across a tumor cell or a cell that is infected with a virus, they surround and destroy the diseased cell by releasing the chemical-containing granules.

This helps the immune system to quickly identify and respond to a previously encountered antigen and provides long-term immunity against specific pathogens. The ____________ function creates the frame that holds the drawing. C. immunosuppressant plasma cells eat invading antigens. In such situations, the innate immune system works with the adaptive immune system to reduce the severity of infection, and to fight off any additional invaders while the adaptive immune system is busy destroying the initial infection. B cells produce specialized proteins called antibodies to counter pathogens. A. bone marrow They digest cells and pathogens by engulfing them in a process called phagocytosis. These two types of receptors are key to the recognition and phagocytosis of microbes. a type of phagocyte which protects the body by ingesting (eating) invading cells and by interacting with the other cells of the immune system: phagocyte: a WBC with the ability to ingest (eat) and destroy substances such as cell debris, dust, pollen, and pathogens: immunity: the state of being resistant or not susceptible to a specific disease Direct link to imma.osime's post https://www.khanacademy.o, Posted 7 years ago.

B. spleanamegaly The entire process, in which the response to particular pathogens modifies certain B cells and T cells, is called adaptive immunity. Phagocytosis: A Fundamental Process in Immunity. This is phenomena known as cellular immunity in which macrophages of body eats the invading cell but before that the foreign cell . At the beginning of phagocytosis, specific molecules or opsonins on the surface of the invading pathogen bind to the receptors on the cell surface of the phagocyte. One example of how an immune response can be detrimental is with fevers that rise to unsafe temperatures, causing tissue damage. A third time immune responses are bad is when our bodies reject medical implants, such as a heart that has been transplanted.
