1.The adaptive immune system consists of humoral immunity and cell mediated immunity.This humoral immunity produces antibodies and the B lymphocytes or B cells functions in it.It also has an acquired immune memory by recognizing the pathogens .The CD4 T cells plays a very important role in adaptive immune system of the body by releasing T cell cytokinase
The innate immune system refers to the presence of immunity naturally from birth and when an infection occurs or a foreign organism enters body it is the one which acts fast.
Ans.can activate quickly
2.The last step of the immune system to a specific bacteria is keeping in memory of the specific bacteria and attacking it in future if exposed by antigen recognition. but only for a short while and can be regained via triggers.
The CD8 cytotoxic /killer T cells after phagocytosis kills the host cell by apoptosis.
IgA acts first in an immune system when encountering a microorganism
Ans:CD cytotoxic /killer T cells destroy host cell containing bacteria

1.Which cells are the link between the innate immune system and the adaptive immune system? 1. A. Memory cells B. Cytotoxic T-cells C. Antigen-Presenting cells D. Endothelial cells 2.Epidemiological clues to the cause of an infectious disease include statistics on: A. age, geographic location, genetics, and sex of victims B. rate and pattern of spread through a population C. time of year D. all of the above
A) lymph follicles lymph nodes C) lacteals D) lymphatics 4) An advantage to adaptive immunity is (A) its memory cells that provide quicker, larger and more efficient immune response upon second and subsequent exposure to an antigen B) its need for several cells to be activated over several days on first exposure C) the ability of its individual cells to respond to many different pathogens D) the use of antibodies that cause cell lysis and kill invading cells 5) A...
Antigen presenting cells link innate and adaptive immune responses. In the theoretical scenario where phagosomes cannot be formed, phagocytosis is made ineffective. a. Would any cytotoxic T cells activity be observed? Explain in less than 25 words.
Antigen presenting cells link innate and adaptive immune responses. In the theoretical scenario where phagosomes cannot be formed, phagocytosis is made ineffective. a. Could any APCs continue processing and presentation of an antigen in this scenario? How? Explain in less than 25 words. b. Would any cytotoxic T cells activity be observed? Explain in less than 25 words. c. Could any antibody production occur? If so, what class(es) could be made? Explain in less than 25 words.
Vaccinations require that humans have which type of immune system? innate immune system adaptive immune system all of the above 10 points QUESTION 2 Which of the following are examples of antigens? one of a group of proteins found in the blood that leads to the clumping of foreign blood cells proteins embedded in the membranes of T cells foreign molecules that trigger antibody production proteins that trigger the end of the inflammatory response 10 points QUESTION 3...
1. Select the statements that correctly describe the role of the thymus, spleen, and lymph nodes in adaptive immunity. Select the TWO answers that are correct. The thymus is the site of T cell development. The thymus and lymph nodes work together in humoral immunity. The thymus and spleen produce B cells. Lymph nodes and the spleen filter pathogens from lymph and blood. The lymph nodes secrete lymphatic fluid. 2. How do humoral immunity and cell-mediated immunity differ? Select the...
1.One group of immune deficiency diseases is caused by an inability of CD8 effector T cells to kill virus-infected target cells, due to defects in cytotoxic vesicle exocytosis. Because of the inflammatory response that accompanies a normal virus infection, together with the prolongation of this response due to the inability to control the infection, patients with these disorders suffer from tissue damage caused by the infiltration of effector CD8 cells and activated macrophages into multiple organs. In addition, a subset...
Question 1: B cells secrete these types of immunoglobulin antibodies. Choose all correct. 1. IgD 2. IgL 3. IgG 4. IgM 5. IgA 6. IgE True or False Questions 2. T cells expressing CD8 protein on their surface are called cytotoxic T cells and function in the killing the infected APC cell. 3. Antigen presentation on the cell surface is a way to tell the immune system that they are infected and the presented molecule tells T cells what they...
