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 does not serve as an antigen-presenting cell?
Red blood cells do not serve as antigen-presenting cells. Antigen-presenting cells include dendritic cells, macrophages, and B cells, which play a crucial role in initiating immune responses by presenting antigens to T cells.
Do plasma cells develop from t cells after exposure to an antigen?
No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.
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?
Naive antigen-nonspecific T cells do not become activated since they lack the T cell receptor specificity for the particular antigen being presented. They do not respond to IL-2 secreted by the activated antigen-specific T cells and remain in a resting state until they encounter an antigen to which they are specific.
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.
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.
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.
What does not serve as an antigen-presenting cell?
Red blood cells do not serve as antigen-presenting cells. Antigen-presenting cells include dendritic cells, macrophages, and B cells, which play a crucial role in initiating immune responses by presenting antigens to T cells.
What type of cells makes blood cells?
antigen
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.
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.
Do plasma cells develop from t cells after exposure to an antigen?
No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.
What are the 3 types of cells that helper t cells produce upon being alarmed of an antigen?
Helper T cells can produce three types of cells when alerted to an antigen: effector T cells, memory T cells, and regulatory T cells. Effector T cells help eliminate the antigen, memory T cells remember the antigen for future responses, and regulatory T cells help regulate the immune response to prevent excessive inflammation.
When you get a cut what do white blood cells fight against?
They phagocytize and isolate any pathogen that may enter the wound.
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?
Naive antigen-nonspecific T cells do not become activated since they lack the T cell receptor specificity for the particular antigen being presented. They do not respond to IL-2 secreted by the activated antigen-specific T cells and remain in a resting state until they encounter an antigen to which they are specific.
