What else can I help you with?
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them called?
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.
The molecules on pathogens that enable the immune system to distinguish one kind of pathogen from another are called?
The molecules on pathogens that enable the immune system to distinguish one kind of pathogen from another are called antigens. Antibodies destroy pathogens by binding to the antigens on the pathogen.
What are protein substances formed in the blood to destroy foreign substances?
Antigens are protein substances formed in the blood to destroy foreign substances. Antigens can also be administered artificially in some cases.
What white blood cells are responsible for recognizing and destroying foreign antigens?
The white blood cells responsible for recognizing and destroying foreign antigens are called lymphocytes. There are two main types of lymphocytes: B cells, which produce antibodies to tag antigens for destruction, and T cells, which directly attack and destroy cells that are infected or presenting foreign antigens.
An immune response in which t cells destroy antigens?
This process is called cell-mediated immunity. T cells, specifically cytotoxic T cells, recognize and destroy cells that are infected with a pathogen or abnormal cells, such as cancer cells. This immune response is crucial for clearing infections and providing immunity against future exposures to the same antigen.
What is he process whereby cells ingest and destroy bacteria within the body called?
Phagocytosis is the process by which cells ingest and destroy bacteria in the body. This process makes up part of the immune function.
What does the thalamus?
it produces the hormones involved in the development of white blood cells called Tcells which form part of the immune system.
What are antigens with only one antigenic site called?
Antigens with only one antigenic site are called Major histocompatibility complex (MHC)
Substances that the body recognizes as foreign are called?
Antigens Antibodies neutralize these molecules.
What are the cells that combine with foreign antigens and present them to t cells called?
Those cells are called antigen-presenting cells (APCs). They include dendritic cells, macrophages, and B cells. Their role is to ingest foreign antigens, process them, and present them to T cells to initiate an immune response.
What process involves antibodies cross-linking cells or particles into large aggregates?
The process is called agglutination. It occurs when antibodies bind to specific antigens on the surface of cells or particles, causing them to clump together or aggregate. Agglutination is commonly used in laboratory tests to detect the presence of specific antigens or antibodies.
Process by which phagocytes destroy pathogens is called?
PhagocytosisPhagocytes make up three-quarters of the body's white blood cells. They destroy pathogens by engulfing them.It's called phagocytosis. Macrophages mainly phagocytose the pathogens.
