Medical Ethics

From Halachipedia

Donating Blood

  1. It is permissible and a mitzvah to donate blood, as it is used to save lives.[1]

Kidney Donation

  1. Since kidney donations aren't so dangerous they are permitted and encouraged.[2]

Heart Transplant

  1. A heart transplant isn't allowed since it is a major dispute if taking a live heart is considered killing the donor.[3]
