Ordinarily, it is not possible to transplant tissues from one person to another, yet corneas can be transplanted without tissue rejection. This is because the cornea has no blood supply.
Though transplanting tissues cannot be done from one person to another, cornea can be transplanted without rejection of tissues because it has no blood vessels.
<u>Explanation:
</u>
The outermost layer of human eyes is Cornea. This is in the shape of a dome and the eye's front portion is covered. It is a major component for the purpose of focusing vision. It has Epithelium which is the outer portion of the cornea.
Bowman's membrane is a layer that lies below the epithelium layer. Stroma, Endothelium and Descemet's membrane are the other parts of cornea. The transplantation of tissues from a human to another human is not possible.
Cornea does not have blood vessel and hence it is possible for the transplantation of cornea from one person to another person.
