eli5 How do cut blood vessels reconnect?

243 views

So I cut my finger with a knife and was wondering, when a vessel gets chopped clean, I believe the side that flows out gets clotted up so you don’t internally bleed. But how do both ends reconnect? Especially if they’re dangling around and no longer aligned. Or do they just… not?? But then wouldn’t that decrease blood flow

Red blood cells help create collagen, which are tough, white fibers that form the foundation for new tissue. The wound starts to fill in with new tissue, called granulation tissue. New skin begins to form over this tissue.

Although there’s a big difference between a cut and actually being lopped off. In the latter, alignment is taken into consideration when reattaching, as misalignment can result in permanently damaging nerve connections.
