ELI5 - how are cuts dealt with in space with zero gravity? is it like the expanse tv show where it becomes difficult for your body to coagulate? Is it any different than on Earth?

Actually the expanse got it right. NASA itself noted that cuts and bruises tend not to heal until the astronauts are back planetside. It's why everything within the space station and space craft is carefully designed to be as low risk for such injuries as possible, but they do happen. When they do they are treated like you normally would but any open cut is left wrapped and the bandage acts like an artificial clot however the natural regeneration of tissue won't occur.

NASA and various medical research scientists are working on ways to overcome the body's lack of healing response in 0g. One way is actually using very specific wavelengths of red light that encourage your cells to produce the appropriate pieces needed to heal.
