#12 The Eye Muscle Is The Fastest Healing Muscle In The Human Body
The cornea of an eye has no blood supply at all. Hence, it gets oxygen directly from the air. The cornea helps in healing any abrasions within 24-36 hours, making it the fastest healing tissue in the human body.
The tongue, however, is the fastest healing external organ. Regular blood supply and the presence of saliva in the mouth keep the wound moisturized and aid rapid healing.
