What is the correct sequence in the inflammatory response?

The correct sequence in the inflammatory response begins with the invasion of a foreign organism, which triggers the body’s immune response. Once the foreign agent is recognized, vasodilation occurs, leading to an increase in blood flow to the affected area. This vascular response enhances the delivery of immune cells and substances needed for healing.

Following vasodilation, the production of fibrinogen clots takes place, which helps to contain the injury site and prevent the spread of infection. Fibrinogen is converted to fibrin, forming a mesh that stabilizes the site and supports healing.

The final step is the migration of phagocytic cells, such as neutrophils and macrophages, to the site of inflammation. These cells are critical for engulfing and destroying pathogens and debris, further aiding in the healing process.

This sequence reflects the body's coordinated response to injury and infection, ensuring an effective defense against foreign invaders while promoting healing.
