Inflammation is the part of the body’s immune response which can be acute or chronic. The inflammatory response: –A. The reassuring feature is that these joint aches do not lead to degenerative joint disease or arthritis. The inflammatory response, or inflammation, is triggered by a cascade of chemical mediators and cellular responses that may occur when cells are damaged and stressed or when pathogens successfully breach the physical barriers of the innate immune system.Although inflammation is typically associated with negative consequences of injury or disease, it is a necessary process … The body's immune reaction to presumed foreign substances like germs. 1st line of defense - skin, mucous membrane, body secretions. Swelling in the ankles, feet and legs is often caused by a build-up of fluid in these areas, called oedema. 2. Insects typically inject formic acid. A defense mechanism that results in redness, heat, pain and swelling. This type of inflammation is characterized by five cardinal signs: heat, redness, swelling, pain, and loss of function. When skin is harmed, for instance, and germs, various other organisms, or harmful materials get in the body… Swelling –B. Common causes of swollen ankles, feet and legs. The swelling happens because small blood vessels allow plasma to go to tissues. Pain –C. When a localized area exhibits increased capillary filtration, hyperemia, and swelling, it is an indication that _____. When inflammation runs rampant, it can disrupt your immune system and lead to a variety of chronic diseases. Inflammation is characterized by increased blood supply and activation of defense mechanisms. Minimizes injury … Inflammation Response; Inflammation is triggered whenever body tissues are injured. The heat and redness show the influx of blood to the affected area. List two lines of nonspecific defense mechanisms with ... inflammatory response is a nonspecific body defense. Heat and redness –D. The increased blood flow to the injured tissue is responsible for the reddish color and is a sign that the healing process is underway.

These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. b. inflammation - sequence of events to limit effects of injury or foreign agent. An insect may bite in self-defense or when looking to feed. Swelling or edema caused by shift of protein and fluid into the interstitial space 3. ... inflammation: basic innate immune response characterized by heat, redness, pain, and swelling. Inflammation is a defense mechanism where the body protects itself from infections or infectious substances, such as bacteria and viruses. The response normally generates inflammation, swelling, heat, as well as discomfort in the target location, and also often the area is disabled. The immune system can be divided into two overlapping mechanisms to destroy pathogens: the innate immune response, which is relatively rapid but nonspecific and thus not always effective, and the adaptive immune response, which is slower in its development during an initial infection with a pathogen, but is highly specific and effective at attacking a wide variety of pathogens … 2nd line of defense . The inflammatory process protects our body from damage and disease by releasing cells and mediators that combat foreign substances and help prevent … One of the nonspecific host defenses is the innate, or inborn, resistance … Some changes occur together one by one. Pain from an increase in pressure of fluid on the nerves, in enclosed areas, and by local irritation of nerves by chemical mediators (like bradykinins) 4. Here it is often the larger joints that ache, compared to neuropathy's onset of pain in the ends of the fingers and toes.
