What stage of inflammation is characterized by vasodilation, increased permeability, leukocytosis, and fever?

The correct understanding of the inflammatory response identifies it as a complex biological process aimed at restoring tissue homeostasis following injury or infection. The stage characterized by vasodilation, increased permeability, leukocytosis, and fever is known as the congestion stage.

During this stage, blood vessels dilate (vasodilation) leading to increased blood flow to the affected area, which causes redness and warmth. Increased permeability of the blood vessels allows for the movement of proteins and fluid into surrounding tissues, contributing to swelling. Leukocytosis refers to the increase in white blood cells, which are crucial for combating infection and promoting healing. Fever is a systemic response that can elevate body temperature to enhance the immune response and inhibit pathogen growth.

This stage is essential as it prepares the tissues for effective healing and recovery. Understanding these processes is vital for studying the general pathophysiological mechanisms of inflammation, especially in the context of health and disease management.
