ELI5: how the heck do you attach new organs inside the body?

I dont know much about surgery and stuff but I'm pretty sure you cant screw an organ into place, gorilla glue arteries together, or tape them together.

You are describing pretty much the procedure that is done when transplanting inn new organs. Just pack it in wherever it fits and attach the arteries and vains as well as any other connections and let the body do the rest. The human body is very robust and can handle a lot of damage. If tissue is cut it will regrow new tissue to connect it back together. Most organs can work even if nerves are being cut. Blood and nerves will be able to reconfigure itself if there are any damages or things move. And even though humans have not had organ transplant for most of our evolution the cells do not know this and will just work like it was any other type of damage.
