The answer are the white blood cells, they are what the body uses to fight off foreign bodies and phagocytic is a word derived from the greek's phag meaning devour and cytic is biological for cell. i hope this helped!
Microglia are small phagocytic cells that are especially obvious in damaged tissue in the central nervous system (CNS). They are the resident immune cells of the CNS and act as the primary form of active immune defense in the brain.
Epidermal dendritic (Langerhans) cells play a crucial role in the immune response, particularly in the skin. They act as antigen-presenting cells, capturing and processing pathogens and foreign substances. Upon activation, they migrate to lymph nodes to activate T cells, contributing to the adaptive immune response. This function is essential for skin immunity and protection against infections.
MHC (Major Histocompatibility Complex) proteins act as a fingerprint of the cell by presenting peptide fragments on the cell surface for immune system recognition. This enables the immune system to distinguish between self and non-self cells, helping to prevent an immune response against the body's own cells.
Microglial cells are the macrophages of the central nervous system (CNS). They act as the primary immune cells in the brain and spinal cord, performing functions like phagocytosis, antigen presentation, and cytokine release to regulate the immune response in the CNS.
The key secretions that control the process of inflammation are cytokines, chemokines, and prostaglandins. These molecules act as signaling agents to recruit immune cells to the site of inflammation, amplify the immune response, and promote the resolution of inflammation.

Antibodies do not play a role in the nonspecific immune response; they are part of the specific immune response, which targets specific pathogens. The nonspecific immune response relies on physical barriers (like skin), phagocytic cells, and other general defenses that act against a wide range of invaders without specificity. Substances like cytokines and complement proteins do contribute to the nonspecific immune response by enhancing inflammation and promoting the destruction of pathogens.
Dendritic cells and macrophages play crucial roles in the immune response within lymph nodes. Dendritic cells act as antigen-presenting cells, capturing and processing antigens from pathogens and then presenting them to T cells to initiate an adaptive immune response. Macrophages help in phagocytosing pathogens and debris, while also presenting antigens to T cells, thereby facilitating the activation and differentiation of these immune cells. Together, they orchestrate the immune response by enhancing communication and coordination between innate and adaptive immune systems.
Cytokines are proteins that act as messengers in the immune system, helping to regulate and coordinate the body's response to infections and other challenges. They can stimulate or suppress immune responses by signaling to different immune cells. This helps to maintain a balanced and effective immune response, preventing overreactions or inadequate responses to threats.
Null cells, primarily referring to natural killer (NK) cells, play a crucial role in the immune system by targeting and destroying virus-infected cells and tumor cells. They are part of the innate immune response and can recognize stressed or abnormal cells without prior sensitization. Additionally, null cells produce cytokines that enhance the immune response and help regulate other immune cells. Their ability to act quickly and independently makes them vital in the body's early defense mechanisms against infections and malignancies.

It provides exterior Form. It helps to Control what goes in and out of the CellDendritic cells are a type of immune cell found in the immune system of mammals. Their main role is processing antigen materials and delivery of these materials to surfaces of other cells.
Yes, proteins can act as antibodies. Antibodies are specialized proteins produced by the immune system that recognize and bind to specific antigens, such as pathogens or foreign substances. This binding helps neutralize the threat and marks it for destruction by other immune cells. Thus, antibodies are a crucial component of the immune response, functioning to identify and eliminate invaders.
