Abstract
When you get a cut, your body immediately activates a process of defense and repair. First, the blood vessels narrow to reduce bleeding, and platelets form a clot that seals the wound. Then, immune cells arrive to clean out bacteria and damaged tissue, causing slight inflammation. Later, the body begins to produce new skin cells, collagen, and blood vessels to rebuild the tissue. Finally, the area is remodeled and strengthened until the skin regains its structure, leaving a scar or not depending on the depth of the injury.
