• A. Easily available
• B. Without blood supply
• C. Easily preserved
• D. Easily stiched

Answer 1

The correct option is B Without blood supply

Cornea is the anterior portion of eye which absorbs oxygen from the air. It is the only part of human body which is devoid of blood supply and absorbs oxygen directly from the air. Due to this reason, cornea can be successfully transplanted and this surgical procedure is known as keratoplasty. The damaged cornea is replaced by healthy or donated cornea and in this procedure there are very less chances of rejection by the immune system.

So, the correct answer is 'Without blood supply'.
