They are "phagocytes." Phagocytes include cells called neutrophils, monocytes, macrophages, dendritic cells, and mast cells.
NEUTROPHILS - first line of defense mechanisms.
MACROPHAGES - second line of defense mechanisms.
Phagocytosis is a process by which macrophages (a type of white blood cells) engulf pathogens and cell debris.

What type of cells phagocytize foreign or injured cell and play a major role in providing protection against infections?
The type of cells that phagocytize foreign or injured cells and provide protection against infections are called phagocytes. This includes various types of cells such as neutrophils, monocytes, and macrophages. They engulf and destroy pathogens and other harmful substances to help eliminate infections.
Hemagglutination-inhibition test description?
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
Cell mediated immunity anatomy definition?
Immunity independent of antibody but dependent on the recognition of antigen by T cells and their subsequent destruction of cells bearing the antigen or on the secretion by T cells of lymphokines that enhance the ability of phagocytes to eliminate the antigen.
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
They proliferate due to their exposure to IL-2
Do plasma cells develop from t cells after exposure to an antigen?
Plasma cells develop from b cells.
What type of cells phagocytize foreign or injured cells and play a major role in providing protection against infections?
macrophages
When langerhans cells phagocytize pathogens where do they carry them to?
Regional lymph nodes where they present to T cells, activating the adaptive immune response.
When langerhans cells phagocytize where do they carry them?
Phagotized pathogen by langerhans cells are carried to the lymphocytes. The lymphocytes are a type of WBC that are located in the lymph nodes.
What type of cells makes blood cells?
antigen
When you get a cut what do white blood cells fight against?
They phagocytize and isolate any pathogen that may enter the wound.
How do B cells respond to the initial antigen challenge?
B cells respond to the initial antigen challenge by producing progeny cells. The progeny cells include both memory cells and plasma cells.
What type of cells phagocytize foreign or injured cell and play a major role in providing protection against infections?

What is the function of an antigen in an antigen-antibody response?
To help immune cells identify and destroy a pathogen
Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
They proliferate due to their exposure to IL-2
