In many college now, for the pre-req courses, students don't need to participate in the dissection of fetal cats, etc. They can use a simulator but I understand it is not easy and very challenging to pass.
As someone who bypassed the medical field as a STEM career because she had no tolerance to ‘blood, guts or icky stuff’ I salute those who can do it.
If you can’t do the icky stuff, choose another career. Your patients won’t be simulations.
