Well, I guess they do, but how much they bleed?
I wonder because few days ago I cut my finger from very sharp blade I blood so much it took about 15 min for the bleeding to stop.
Doesn’t it happen in surgery? How they handle this?

It depends on the specific surgery. The goal is always to keep blood loss to a minimum. For minor procedures the blood loss can be minimal, for more invasive procedures the blood loss can be light to moderate depending on the surgery.

Edit: it’s also important to note that when major blood loss occurs, it’s because a main blood vessel was punctured. If this doesn’t occur then blood loss is usually minimal.

I know it might seem like a lot of blood loss when you cut your finger, but it really isnt. Your body has a lot.

They clamp major blood vessels but also they have a special scalpel that cauterized blood vessels as they are cut, so the blood vessels are sealed and bleeding is kept to a minimum.
