Homework Answers
a. B cells; B cells are specialized B lymphocytes which produces antibodies.
b. Helper T cells; Helper T cells are T lymphocytes which binds to specific antigen and secrete chemicals to stimulate other immune cells to fight.
c. Cytotoxic T cells; Cytotoxic T cells are T lymphocytes which is also known as killer cells. When activated it destroys the infected cells.
d. Macrophages;Macrophages are large white blood cells which may directly engulf the pathogens like bacteria, viruses etc.
e. Antigen presenting cells; Antigen-presenting cells (APCs) are a heterogeneous group of immune cells which represent antigens to certain lymphocytes for recognition.

Match each type of immune system cell to its function or description. (Use each description once). Helper T-cell Detects pathogens and releases chemokines as part of the inflammatory response Participates in activation of B-cells if it has receptors for the same antigens Has receptors that are specific to particular antigen structures and releases antibodies as part of the humoral response Releases histamine as part of the inflammatory response Secretes proteins that cause infected cells to undergo apoptosis White blood cell...

Type I (acute) hypersensitivity Type II (cytotoxic) hypersensitivity Type III (immune complex) hypersensitivity Type IV (delayed) hypersensitivity Answer Bank Antigens bind to IgE on basophils and mast cells and stimulate them to secrete vasoactive substances. IgG or IgM binds to an antigen, which leads to lysis or opsonization of target cell. T cells elicit a response 12-72 hours after initial exposure. Anaphylactic shock is an example of this type...

QUESTION 11 How is the immune system able to recognize a limitless number of different antigens and epitopes? While each lymphocyte carries receptors that recognize only one type of epitope, the immune system produces a wide variety of lymphocytes each of which carries unique receptors A genetic "memory" of the pathogens your parents encountered (and their parents and so on) is passed on to each generation, increasing the number of possible responses over time. Each lymphocyte is coated with many...
