Antigen - a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies
Antibody - a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
Apoptosis - the death of cells which occurs as a normal and controlled part of an organism's growth or development.
Autoimmune disease - Autoimmune disease happens when the body's natural defense system can't tell the difference between your own cells and foreign cells, causing the body to mistakenly attack normal cells. There are more than 80 types of autoimmune diseases that affect a wide range of body parts.
B-cell - B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system.
T-cells - T cell, also called T lymphocyte, type of leukocyte (white blood cell) that is an essential part of the immune system. T cells are one of two primary types of lymphocytes—B cells being the second type—that determine the specificity of immune response to antigens (foreign substances) in the body.
Helper - A type of immune cell that stimulates killer T cells, macrophages, and B cells to make immune responses. A helper T cell is a type of white blood cell and a type of lymphocyte. Also called CD4-positive T lymphocyte.
Killer - A type of immune cell that has granules (small particles) with enzymes that can kill tumor cells or cells infected with a virus. A natural killer cell is a type of white blood cell. Also called NK cell and NK-LGL.
Supresor - A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. If the cell grows uncontrollably, it will result in cancer. When a tumor suppressor gene is mutated, it results in a loss or reduction in its function.
Memory - Memory is the ability of the brain to encode, store and retrieve information when required.
Leukocyte - A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease.
Erythrocyte - A blood cell with hemoglobin-rich cytoplasm and whose main function is to transport respiratory gases, chiefly oxygen
Lymphocyte - a form of small leucocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.
Lymph nodes - Lymph nodes are located in many parts of the body, including the neck, armpit, chest, abdomen (belly), and groin. They contain immune cells that can help fight infection by attacking and destroying germs that are carried in through the lymph fluid. There are hundreds of lymph nodes throughout the body.
Macrophage - a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.
Mast cells - Mast cells are blood cells that are part of your immune system. They help you fight infections, but they are also involved in allergic reactions. Mast cells live longer than normal cells, and they grow in your bone marrow, your gastrointestinal tract, your skin, and your airways.
Pathogen - A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.
Phagocyte - A pathogen is defined as an organism causing disease to its host, with the severity of the disease symptoms referred to as virulence. Pathogens are taxonomically widely diverse and comprise viruses and bacteria as well as unicellular and multicellular eukaryotes.
I spent so long on this and I think I even did the other ones that the other guy didn’t do brainliest would be appreciated!
Hope I helped !
