What characterizes the coagulation phase of wound healing?

• A. Development of scar tissue
• B. Vasodilation, tissue repair, and healing
• C. Vasoconstriction, platelet aggregation, and clot formation
• D. Formation of new blood vessels

Answer: (C)

The coagulation phase of wound healing is primarily characterized by vasoconstriction, platelet aggregation, and clot formation. During this initial phase, which occurs immediately after tissue injury, blood vessels constrict to reduce blood loss. Platelets rapidly aggregate at the injury site and become activated, releasing various substances that promote clot formation. This forms a fibrin clot, which serves not only as a temporary barrier to prevent further bleeding but also offers a matrix for incoming cells that will be crucial in the subsequent phases of healing. The significance of this phase cannot be overstated, as it sets the foundation for the healing process. The clot not only halts blood loss but also serves as a scaffold for the migration of cells necessary for tissue repair and regeneration. The coagulation phase is a vital initial response in the body's healing process, emphasizing the importance of these physiological responses in wound management.
