Vascular changes in the early inflammatory phase involve rapid shifts in blood flow and increased permeability to help immune cells reach the injury. The sequence starts with brief vasodilation, which increases blood flow to the area and brings warmth and redness. This is followed by changes that make the vessel walls more permeable, allowing plasma proteins and fluids to leak into the surrounding tissue and creating space for immune cells to exit the vessels. Platelets also aggregate at the injury site, forming a temporary plug and releasing mediators that amplify the inflammatory response and support subsequent healing. This combination—initial vasodilation, increased vascular permeability, and platelet aggregation—best describes the vascular events of the inflammatory stage, making it the correct description among the options.
