Sure! I'd be happy to help you with your questions about immunology: 1. What is the function of the innate immune system? The innate immune system is responsible for providing immediate, non-specific defense against pathogens. It acts as the first line of defense and includes physical barriers (such as the skin), chemical barriers (such as antimicrobial proteins), and cellular components (such as phagocytes). 2. How can NK cells recognize infected or abnormal cells in tissues? Natural Killer (NK) cells can recognize infected or abnormal cells through a process called "missing self-recognition." They detect cells that have reduced or altered expression of major histocompatibility complex (MHC) class I molecules, which are normally present on healthy cells. This allows NK cells to identify and eliminate cells that may be infected or cancerous. 3. What do we call the foreign particles that enter our body and stimulate our immune system? Foreign particles that enter our body and stimulate our immune system are called antigens. Antigens can be proteins, carbohydrates, lipids, or other molecules that are recognized by the immune system as non-self. 4. What is an attribute of the innate immune system, and not the adaptive one, of the host defense system? One attribute of the innate immune system, and not the adaptive immune system, is its rapid response. The innate immune system provides immediate defense upon encountering a pathogen, whereas the adaptive immune system takes time to mount a specific response. 5. What is incorrect regarding the immunology of transplants? I'm sorry, but you haven't provided any specific options or statements regarding the immunology of transplants. Please provide more information or options so that I can help you with this question. If you have any more questions or need further clarification, feel free to ask!
