Answer 1

If big blood vessels are physically clamped off so no blood flows through them. Smaller blood vessels are cauterised so the don’t leak.

Surgeons go carefully so they do their best not to accidentally cut a blood vessel. If one does get cut by mistake they try to clamp it off as quickly as possible to reduce blood loss.
