acute inflammation Flashcards
What is acute inflammation?
A rapid and early response to tissue injury or infection characterized by redness, heat, swelling, pain, and loss of function.
True or False: Acute inflammation is a chronic process.
False
List the cardinal signs of acute inflammation.
Redness, heat, swelling, pain, and loss of function.
What type of immune cells are primarily involved in acute inflammation?
Neutrophils.
Fill in the blank: The primary purpose of acute inflammation is to _______.
eliminate the initial cause of cell injury.
What role do cytokines play in acute inflammation?
They are signaling molecules that mediate and regulate immunity and inflammation.
Multiple choice: Which of the following is NOT a characteristic of acute inflammation? A) Redness B) Swelling C) Long duration D) Pain
C) Long duration
What is the first step in the acute inflammatory response?
Vasodilation of blood vessels.
True or False: Acute inflammation can lead to the formation of granulomas.
False
What is the role of histamine in acute inflammation?
Histamine causes vasodilation and increased permeability of blood vessels.
Fill in the blank: Acute inflammation typically resolves within _______.
a few days to weeks.
What are the common causes of acute inflammation?
Infections, trauma, chemical exposure, and immune reactions.
Multiple choice: Which cell type is primarily involved in the cleanup phase of acute inflammation? A) Neutrophils B) Macrophages C) Lymphocytes D) Eosinophils
B) Macrophages
What is the significance of exudate in acute inflammation?
Exudate contains proteins, cells, and other substances that help facilitate the inflammatory response.
True or False: Acute inflammation can be beneficial to the healing process.
True
What is the difference between acute and chronic inflammation?
Acute inflammation is a short-term response, while chronic inflammation is a prolonged and often inappropriate response.
Fill in the blank: The presence of _______ in the tissue indicates acute inflammation.
neutrophils.
What is the typical duration of acute inflammation?
Days to weeks.
Multiple choice: Which of the following mediators is NOT typically involved in acute inflammation? A) Prostaglandins B) Leukotrienes C) Interferons D) Cytokines
C) Interferons
What is the main function of prostaglandins in acute inflammation?
They promote vasodilation and increase blood flow to the affected area.
True or False: Acute inflammation can lead to tissue repair.
True
What is the role of bradykinin in acute inflammation?
It increases vascular permeability and causes pain.
Fill in the blank: The inflammatory response is initiated by the release of _______ from damaged tissues.
chemical mediators.
What is the primary goal of acute inflammation?
To eliminate the cause of injury and begin tissue repair.
Multiple choice: Which type of inflammation is characterized by the formation of pus? A) Acute B) Chronic C) Granulomatous D) None of the above
A) Acute
What is a common systemic effect of acute inflammation?
Fever.
True or False: Acute inflammation can occur without an infection.
True
