Question 1
Multiple choiceWhat is the primary purpose of acute inflammation in the body?
Explanation
The primary purpose of acute inflammation is to eliminate the initial cause of cell injury and to initiate tissue repair.
Question 2
Multiple choiceWhich of the following is NOT considered a classic sign of acute inflammation?
Explanation
Bruising (ecchymosis) is not one of the classic signs of acute inflammation, which include redness, heat, swelling, pain, and loss of function.
Question 3
Multiple choiceDuring the vascular response in acute inflammation, what happens to blood vessels?
Explanation
During the vascular response, blood vessels dilate and become more permeable, allowing immune cells to reach the injury site.
Question 4
Multiple choiceWhich immune cells are primarily involved in the acute inflammatory response?
Explanation
Neutrophils and macrophages are key players that migrate to the affected area during acute inflammation to eliminate pathogens and clear debris.
Question 5
Multiple choiceWhat role do cytokines play in acute inflammation?
Explanation
Cytokines are chemical mediators that regulate the inflammatory response and help recruit additional immune cells to the injury site.
Question 6
Multiple choiceWhat common misconception exists regarding inflammation?
Explanation
A common misconception is that all inflammation is harmful and should be suppressed, while in fact, acute inflammation is a protective response crucial for healing.
Question 7
Multiple choiceWhat happens during the resolution phase of acute inflammation?
Explanation
During the resolution phase, anti-inflammatory signals help regulate and conclude the inflammatory process once the injury is resolved.
Question 8
Multiple choiceWhich example demonstrates the role of acute inflammation in infection response?
Explanation
The formation of pus during a bacterial infection illustrates how acute inflammation helps contain and eliminate pathogens.
Question 9
Multiple choiceIn acute inflammation, the term 'loss of function' can refer to which of the following?
Explanation
Loss of function during acute inflammation refers to a temporary impairment that can occur based on the location and severity of the inflammatory response.
Question 10
Multiple choiceHow does acute inflammation facilitate tissue repair after injury?
Explanation
Acute inflammation facilitates tissue repair by allowing immune cells to migrate to the site of injury and clear out debris, thus promoting healing processes.
