1. The specific immune response is the second line of defense after anatomical and chemical barriers. involves memory of antigens from previous exposure. is the first line of defense in the immune system. involves millions of B and T cells – each individual cell can recognize many different antigens. 2. T cells arise and finish development in the bone marrow. all carry out the same function. are responsible for cell-mediated immunity. make antibodies. 3. Antigens are universal molecules shared by many microbes. are only found inside or on the surface of microbes. are molecules that can be recognized by B- or T-cells. refers to any molecule found inside the body.

The specific immune response is the second line of defense after anatomical and chemical barriers. This statement is true. The first line of defense includes physical and chemical barriers like skin, mucous membranes, and secretions. The specific immune response Show more…

Match the features of each of the three levels of defense of your immune system. Cells that first respond to pathogens after entering the body: A 2nd Line of Defense (Innate) Cells recognize a broad variety of pathogens with non-specific responses. B. 1st Line of Defense (Physical) Includes cells such as basophils macrophages, and dendritic cells. C 3rd Line of Defense (Adaptive) Includes cells such as Helper T cells, Memory B & T cells, Cytotoxic T cells, and Natural Killer Cells Cells recognize specific pathogens and target them for destruction. Cells initiate responses after receiving information from the first responder cells. Includes your skin and mucus membranes Prevents outside pathogen entry into the body by physically blocking or trapping them before they can infect the cells:
Adi S.
All of the following are true of antibodies EXCEPT they are recognized by phagocytes they destroy virus-infected cells they can block pathogens from infecting cells they bind to specific antigens The innate and adaptive immune response systems work together to defend against pathogens. Which statement is false? Lymphocytes are the primary cells responsible for adaptive immunity. The adaptive immune response is greater after the second exposure to a specific pathogen. The adaptive immune response is important in fighting specific pathogens. The innate immune response is only effective against the primary exposure to a pathogen. _______ immunity provides general defense against a variety of pathogens, whereas _______ immunity provides defense against specific pathogens. Humoral; innate Adaptive; innate Innate; cellular Innate; adaptive Cellular; adaptive
