Inflammation is an important component of the innate defense reaction. Identify the words that correctly complete each sentence regarding the steps of the inflammatory response. prostoglandins integrins diapedesis osmosis progesterones chemokines neutrophils selectins chemotaxins edema margination The acute inflammatory response begins when injured tissue releases chemical signals called ______. These signals stimulate the cells lining the capillaries to display ______ on their surface, which attract wandering ______. These white blood cells produce ______, which allow them to bind to the selectin-positive epithelial cells in a process called ______. The stuck cells then squeeze through the capillary wall in the process of ______. After this migration occurs, other white blood cells are then attracted to the area by the release of ______. In addition to these molecules, bradykinin is released into the area causing the production of ______ that advance the inflammation response. In response, capillaries dilate and fluids move into the surrounding tissues creating swelling called ______.

The inflammatory response is an innate reaction to invasion by a pathogen regardless of whether that pathogen had been previously encountered. Which statement best describes the symptoms of redness and swelling at the site of a splinter after its removal? A) Interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling. B) Interactions of the respiratory and immune systems create an increased breathing rate and immune cell metabolism, which can lead to redness and swelling. C) Interactions between the immune system and digestive system increase the digestive enzyme activity at the site of the infection, which leads to redness and swelling. D) Interactions of the immune system and nervous system lead to increased cellular communication and hormonal activity at the site of the infection, which causes redness and swelling.

All but one of the following occur during the inflammatory response. Select the example below that does not describe the process of inflammation A) Increases capillary permeability B) Release of prostaglandins resulting in pain: C) Chemotaxis draws leukocytes to the site of injury: D) Vasoconstriction will prevent excessive blood loss due to injury: 27) Membrane attack complex (MAC) kills bacteria by A) allowing the organelles to spill free from the bacterial cells B) penetrating the capsule of the bacteria and entering the bacterial cytosol, providing passage for antibodies to enter the bacteria plasma membrane C) disrupting the selectively permeability of the bacterial cytoplasmic membrane D) preventing the replication of viral cells 28) Interferons produced against one specific virus A) are effective against another virus, such as the common cold B) are routinely used in nasal sprays to increase the rate of cell division C) act by increasing replication within cells to interfere with viral replication

The overall role of the inflammatory response is to a. contain and eliminate foreign cells and material at the site of infection. b. increase heat at the site of infection to activate enzymes used in the immune response. c. produce antibodies that bind to and eliminate invading cells. d. increase blood flow at the site of a wound to flush out invading pathogens.
