Questions and Answers
Which physiological process exemplifies a localized inflammatory response aimed at tissue repair rather than a systemic immune activation?
Which physiological process exemplifies a localized inflammatory response aimed at tissue repair rather than a systemic immune activation?
- Vasodilation causing redness and heat around a skin laceration. (correct)
- Development of a high fever in response to a systemic bacterial infection.
- Increased antibody production by plasma cells in response to a viral infection.
- The release of acute phase proteins by the liver during a widespread infection.
How does a moderate fever contribute to the body's defense mechanisms, beyond merely inhibiting microbial growth?
How does a moderate fever contribute to the body's defense mechanisms, beyond merely inhibiting microbial growth?
- By directly neutralizing bacterial toxins through thermal denaturation.
- By selectively inhibiting the replication of all viruses, regardless of their temperature sensitivity.
- By enhancing the mobility and activity of leukocytes, thereby accelerating the immune response. (correct)
- By inducing a state of hibernation in immune cells, conserving energy for future battles.
In the context of inflammation, which cellular event primarily contributes to the sensation of pain?
In the context of inflammation, which cellular event primarily contributes to the sensation of pain?
- The stimulation of nociceptors by inflammatory mediators such as bradykinin and prostaglandins. (correct)
- The phagocytosis of pathogens by macrophages, reducing the microbial load.
- The release of histamine causing vasodilation and increased blood flow.
- The increased proliferation of fibroblasts leading to scar tissue formation.
Considering the dual nature of fever as both a defense mechanism and a potential threat, which scenario necessitates immediate medical intervention?

Study Notes
Inflammation
- Inflammation is a non-specific response to tissue trauma.
- Signs of inflammation include heat, swelling, redness, and pain.
- Inflammation mobilizes immune system components, initiates repair mechanisms, and attracts phagocytes to destroy microorganisms.
Fever
- Fever is a nonspecific defense mechanism triggered by various traumas.
- Pyrogens, circulating substances, initiate fever by affecting the hypothalamus.
- The hypothalamus raises body temperature.
- While excessive fever is dangerous, fever benefits by slowing microbial growth.
- Fever boosts body cell metabolism and stimulates the immune response.
