(a) In tobacco-associated chronic obstructive pulmonary disease (COPD), is the ability of the body to respond to reactive oxygen species increased or decreased? I would choose "increased", but not sure if I am correct. (b) In tobacco-associated COPD, is the innate immune system aberrantly activated or depressed? I would choose "depressed", but not sure.

What is the role of dendritic cells in the innate immune system?
Fill in the blanks: When tissues are damaged, macrophages release inflammatory mediators that cause -------,-------, and -------. Certain inflammatory mediators called ------ increase the hypothalamus "set point" for temperature and cause fever.
A hypothetical disorder prevents memory cells from forming. What effect would this have on the immune system? B lymphocytes would be affected, but not T lymphocytes, Vaccinations would no longer be useful, The inflammatory response would no longer be effective, or The adaptive immune response would cease to function, but the innate immune response would continue to function normally.

Why is iron availability important in body defenses?
Explain why each choice (a-d) is correct or incorrect. All but one of the following occurs during the inflammatory response. Select the example below that does NOT describe the process of inflammation. a. Inflammation increases capillary permeability. b. Chemotaxis draws leucocytes to the site of injury. c. Vasoconstriction prevents excessive blood loss due to injury. d. Release of prostaglandins results in pain.
What is the role of T cell, B cells, and Natural killer cells in the function of the Immune system?
During the chemotaxis phase of the inflammatory response,a. C-reactive protein is secreted by damaged parenchymal cells in the tissue, which attracts neutrophils, which secrete leukotrienes and prostaglandins to attract macrophages; a purulent exudate is formed.b. Band cells respond to hyperthermia by producing TNF-α and interleukins, which then cause a left shift that results in the accumulation of neutrophils within the tissue.c. Damaged parenchymal cells release prostaglandins and leukotrienes to attract macrophages, causing a left shift and the formation of a purulent exudate.d. Cytokines, such as TNF-α, are released by damaged parenchymal cells, while leukotrienes and prostaglandins produced by neutrophils cause smooth muscle constriction and the further accumulation of leukocytes.
