5 Questions
What are the two types of antigens mentioned in the text?
The two types of antigens mentioned are self antigens and non-self antigens.
Explain the difference between innate and adaptive immune responses as described in the text.
The innate immune response refers to the body's initial, nonspecific defense mechanisms, including physical barriers (skin, hair, cilia), chemical barriers (stomach acid, lysosome, mucus), and cellular responses (phagocytes). The adaptive immune response, on the other hand, is a specific defense mechanism involving active (memory cells produced) and passive (no memory cells produced) responses, triggered by exposure to pathogens or through vaccination.
What are the two ways through which infectious diseases can spread, according to the text?
Infectious diseases can spread through droplets or fluids, and they can spread epidemically (in only a few regions) or pandemically (in most regions of the world).
Describe the process of how the immune system recognizes the difference between self and non-self antigens, as discussed in the text.
The immune system recognizes the difference between self and non-self antigens based on the presence of protein molecules (antigens) on the surface of cells. Self antigens are substances produced by the body and do not stimulate the immune system, while non-self antigens are foreign proteins that trigger an immune response.
What are the three types of barriers in the innate immune response, as mentioned in the text?
The three types of barriers in the innate immune response are physical barriers (skin, hair, cilia), chemical barriers (stomach acid, lysosome, mucus), and cellular responses (phagocytes, including neutrophils and monocytes).
