Concept explainers
To predict: The changes that occur when no NK cells are present in the body.
Concept introduction: A complex network of cells, tissue, and organs that work collectively for the protection of body and fight against the pathogens or foreign substances is called the immune system. Immune cells are the cells that actively participate in the defense mechanism initiated by the immune systems. One such major type of immune cells is lymphocytes.

- In an immune response, what is the main function of the circulatory system? to produce inflammation and activate B cells to send chemical signals and transport immune cells to stimulate infected cells and release interferons to trap pathogens and attract phagocytesarrow_forwardCompare and contrast cytotoxic T cells and NK cells?arrow_forwardGive typing answer with explanation and conclusion using the metaphor of an army,what is the difference between the lymphatic and immune systems?arrow_forward
- Which is true of the innate immune response? a) Mucus can contain lysozyme and ampicillin b) Fe poisons potential pathogens c) Skin is dry and alkaline d) Fe limitation has a bacteriostatic effectarrow_forwardWhich is the proper order of events in cell-mediated immunity? (1) Cloning of cytotoxic T cells and memory T cells(2) Antigen presented to T lymphocyte(3) Activation of T lymphocytes(4) Cytotoxic T cells attack target cells Select one: a. 3, 2, 4, 1 b. 1, 4, 2, 3 c. 2, 3, 4, 1 d. 2, 3, 1, 4 e. 1, 2, 3, 4,arrow_forwardWhat is the role of Role of NK Cells?arrow_forward
- How do corticosteroids act to block inflammation? a. Blocking neutrophil migration b. Blocking mast cells degranulation c. Blocking macrophage activation d. Blocking the synthesis of arachidonic acidarrow_forwardDescribe neutrophils and NK cells, giving one example of how each cell type destroys pathogens that have invaded your body. Why are they both part of the “innate” immune system?arrow_forwardWhich is/are function(s) of the lymphatic system? a. Hemopoiesis b. Inspect lymph for pathogens c. Regulation of blood pressure d. Collect interstitial fluid and return it to the blood circulatory systemarrow_forward
- fever helps the body fight infection in which of the follwoing ways? a. fever causes the creation of lysosomes b. increased body temperature decreases phagocytosis c. fever inhibits the growth of some microorganisms d. fever increases capillary permeabilityarrow_forwardPhagocytes move through capillary walls by squeezing between adjacent endothelial cells, a process known as (a) diapedesis. (b) chemotaxis. (c) adhesion. (d) perforation.arrow_forwardGive typing answer with explanation and conclusion how is the development of autoimmunity normally prevented? a. T lymphocytes require a specific set of cytokine signals to become activated b. regulatory T cells suppress autoimmune responses c. clonal deletion of T cells and regulatory T cell suppression prevent auto reactive T cell activation d. clonal deletion of T cells, lack of necessary cytokine signals, and regulatory T cell suppression prevent activation of auto reactive T cellsarrow_forward
