Your heart is an incredibly hardworking organ. In five minutes, it will pump five litres of blood around your body.
Many people would probably think it's the heart, however, it's the brain! While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body.

Vestigial organs are parts of the body that once had a function but are now more-or-less useless. Probably the most famous example is … the appendix, though it is now an open question whether the appendix is really vestigial.
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
Answer and Explanation: The mouth is the fastest healing organ, according to Brand et al. (2014). This is due to the presence of saliva, that moisturizes the wound, improves immune response to wound healing, and contains other wound-healing promoting factors.
