Figure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.
The Adaptive Immune Response Is a Specific Defense Against Infection Identify the components of cellular immunity, and define their roles in the immune response.
This graph is illustrating the principle that: Secondary response (d) Primary Response anitbody concentration required for immunity (a) (b) (c) Time after infection 10 20 30 40 20 + Second Infection 10 30 40 in days First Infection delay your body can respond with more antibodies faster the second time it sees an antigen O all of the other answers O antibiotics won't work for viruses vaccines will not work for viruses the second infection is always much worse than the first infection Antibody concentration in blood
the 3rd line of defense please describe how each side is activated and what happens all the way to the end. please include the importance of the 3rd line and what adaptive immunity means. please explain the Humoral side from recognition of the antigen all the way to after the antibodies bind the antigen and the Cellular side from the recognition of the antigen all the way to when the host cell implodes. thank you i dont really understand can you explain it in simple terms
The figure below shows the primary and secondary immune responses to an antigen. Which of the following is NOT shown or implied by this figure? Antibody titer in serum (arbitrary units) - 1st Ag Exposure IgM IgG 14 Time (days) - 2nd Ag Exposure 21 58 65 None of the other four answers (All are shown or implied by the figure) IgG is the predominant class of antibody produced after second exposure to the Ag The second exposure to an Ag results in higher IgG levels than the first exposure IgM is the first class of antibody produced after first exposure to the Ag Memory B cells produced upon the first exposure to an Ag can react quickly to subsequent exposures to the same Ag 72

Which of the following is true about the immune system? CHeck all that apply. Neutrophils are abundant granulocytes that phagocytose bacteria, whereas eosinophils eliminate helminth parasites Anatomic barriers include epithelial cells, macrophages, dendritic cells Dendritic cells and macrophages are phagocytic cells that can present antigen T lymphocytes Innate immune cells are macrophages, granulocytes, natural killer cells and adaptive immune cells are B and T cells B and T cells originate from myeloid progenitor, whereas monocytes and neutrophils from lymphoid progenitor.
■ Which of the following is considered an innate immunity. Production of antibodies via B lymphocytes Killing virally infected cells by cytotoxic T lymphocyte The protective action of lysozymes in tears and saliva [ All of the above
eds Antibodies (Immunoglobulins) Objective 14 Antibodies (immunoglobulins) are glycoproteins secreted by plasma cells. They are located in interstitial fluid, plasma (gamma globulin fraction) and in body secretions. onse A. Antibody Structure Heavy chain Antigen-binding site Light chain Insmakamos Hinge region Complement- binding site Stem region Macrophage binding site OHO (a) Antibody molecule OHO X = Disulfide bond Carbohydrate four polypeptide chains (two heavy, two light) chains are held together by covalent disulfide bonds (S=S) each heavy chain and each light chain has two functional areas: consists of highly variable amino acid sequences which forms the basis of antibody specificity; antigen binds here ????? to more conserved amino acid sequences; there are five basic sequences of amino acids, which define the 5 antibody classes (IgG, IgA, IgM, IgE and IgD); ????? each class has its own characteristic set of effector functions (see next page) Your notes: 4 40 4. 39
