What occurs during the hemostasis phase of wound healing?

• A. Immediate vasodilation and clot formation with minimal exudate.
• B. Immediate vasoconstriction, blood clot formation, and development of exudate.
• C. Proliferation of fibroblasts and collagen deposition.
• D. Epithelialization without inflammation.

Answer: (B)

When a wound first happens, the body’s immediate aim is to stop the bleeding and lay down a temporary matrix for healing. Vessels constrict right away to reduce blood loss, and platelets rush to the site to form a plug. Along with this, the coagulation cascade activates and a fibrin clot forms, creating a solid framework that seals the wound and provides a scaffold for the next steps in healing. As this early hemostatic response unfolds, inflammatory signals kick in and capillaries become more permeable, allowing fluid—the beginning of exudate—to escape into the tissue. This combination of rapid constriction, clot formation, and the start of exudate aligns with the first phase of wound repair. The other options describe processes that belong to later phases (like fibroblast activity and collagen deposition in proliferation, or epithelialization without inflammation) or misstate the timing of vasodilation versus vasoconstriction and exudate.
