Which of the following best describes the vascular phase of acute inflammation? A) It is characterized by prolonged vasodilation and increased blood pressure. B) It requires leukocyte activation and adhesion to endothelial cells. C) It involves rapid vasoconstriction followed by steady vasodilation. D) It includes changes in blood vessels, leading to heat, redness, and swelling.
Understand the Problem
The question is asking for the best description of the vascular phase of acute inflammation among the given options. We need to evaluate each option in the context of what the vascular phase entails.
Answer
It involves rapid vasoconstriction followed by steady vasodilation.
It involves rapid vasoconstriction followed by steady vasodilation.
Answer for screen readers
It involves rapid vasoconstriction followed by steady vasodilation.
More Information
The vascular phase of acute inflammation is characterized by an initial rapid vasoconstriction followed by prolonged vasodilation. This vasodilation leads to increased blood flow to the affected area, causing heat and redness, and results in the leakage of fluids, causing swelling.
Tips
A common mistake is confusing vascular responses, assuming initial vasodilation occurs immediately without transient vasoconstriction.
