APSM CA Biology 3.8 Immune System
| Term | Definition |
|---|---|
| AIDS | serious immune deficiency disease caused by HIV |
| Allergy | occurs when immune system overreacts to foreign substances like pollen, dust, or food |
| antibiotic resistance | pathogens that can’t be killed by antibiotics because of widespread overuse |
| antibiotics | substance produced by bacteria, mold, etc that stops the growth of microorganisms |
| antibodies | y-shaped protein molecule that binds to pathogen antigens to inactivate pathogens and mark them from destruction |
| antigens | carbohydrate molecule on the surface of a cell that functions as an identification tag |
| antihistamine | used to treat the overproduction of histamine due to allergies |
| asthma | chronic allergic reaction of respiratory tract leading to narrowing of air passages |
| autoimmune disease | immunological disease in which the immune system attacks the body |
| B cells | lymphocytes that make antibodies in response to antigens |
| emerging disease | diseases that we didn’t know about before |
| histamine | chemical messenger produced by white blood cells, causes inflammation |
| Human Immunodeficiency Virus (HIV) | virus that causes AIDS, destroys T cells that recognize pathogens |
| immune response | process by which your immune system recognizes & destroys pathogens |
| immune system | body system that defends against bacteria, viruses, and other invader |
| infectious disease | diseases caused by pathogens |
| lymphocytes | white blood cell the produces antibodies |
| memory B cells | B lymphocyte that forms after an infection and remembers the pathogen, allowing for faster antibody production during future infections |
| memory T cells | subset of T lymphocyte that forms after an infection and remembers the pathogen, allowing for faster antibody production during future infections |
| model organism | non-human species studied to understand particular biological phenomena |
| pathogen | any organism that causes disease |
| public health | rules and laws designed to control spread of infectious disease |
| rheumatoid arthritis | chronic autoimmune disease causing inflammation of joints; causes swelling, stiffness, and alteration of the affected joints |
| surface molecules | molecules, such as proteins and lipids, located on the surface of cells; crucial for cell communication, interaction, and function |
| T cells | lymphocytes that destroy pathogens and send signals that help coordinate your immune system’s response to threats |
| toxin | naturally occurring poison produced by metabolic activities of living cells |
| vaccination | process of using a vaccine to prevent the spread of a disease |
| zoonosis | passing disease from animal to human |
