The idea
Wounds heal by primary, secondary or tertiary intention, depending on how they are closed.
In practice
Primary: edges closed together. Secondary: edges cannot meet, so the wound fills in from the bottom. Tertiary: left open or reopened, often for infection, and closed later.
Where people slip
Secondary and tertiary healing take longer and leave more scar, and open wounds must be protected from contamination.
