What happens once the newly made antibodies find and attach to the antigen? What are the 5 possibilities. Explain how memory cells help to speed up future immune responses to pathogens the body has already seen, and how much the immune response is sped up by. Use the terms primary and secondary immune response in your answer.

Part E - Characteristics of Lymphocytes Drag and drop the correct type of immunity on the left to complete the sentence that describes the targets, actions, or cell associated with that type of immunity. Immunity types may be used more than once, but each sentence has only one correct type of immunity associated with the description. View Available Hint(s)

Select the best answer or answers from the choices given: Cells that can directly attack target cells include all of the following except (a) macrophages, (b) cytotoxic T cells, (c) helper T cells, (d) natural killer cells.

__________________________________________________ cells can help prevent autoimmune diseases. The antigen receptor on a B cell is essentially a membrane-bound ____________________________.  If a cell of yours lacks MHCs, ______________________________________  (specific kind of cell) might cause its death _________________________________ is the name of the migration activity by a neutrophil, e.g., when it is physiologically driven to move toward molecules at an area of injury. Its temporary binding and unbinding to sticky endothelial cell adhesion molecules on their way is called _______________________________________. When it enters the injured or infected tissue space from the capillary this is called ____________________________________. When identical plasma cells start being made, in great abundance, from a single specific immune cell, the originally chosen immune cell has undergone ______________________ - ______________________________________. What are a few things discussed…

Select the correct answer from the answers provided. The cross-linkage of antigens by antibodies is known as a. opsonization b. a cross-reaction c. agglutination d. complement fi xation

The inflammatory response is a vital component of non-specific immunity. Describe how the inflammatory response is triggered and the major events that follow. Include in your answer the critical molecular and cellular factors involved in the response. Complement, when activated, plays an important role in both specific and non-specific immune responses. Briefly describe the 3 key activities that complement, once activated, can play in protective immunity. (Please answer in dot point format. Thanks)

Match the type of lymphocyte cell with its main function in the immune system. Generates antibodies [ Choose] [Choose ] T cells Secretes cytokines Antibody B Cells NK cells Secretes cytotoxic granuales [ Choose ] Binds specific antigen [ Choose ]

Write T if the statement is correct. Write F if the statement is incorrect.     B cells can be activated only by TH2 cells and not by TH1 cells.
