Question
Which is the only part of the human body that does not get oxygen from blood but directly from air?
Show Answer & Explanation
Answer: Cornea (the transparent front part of the eye)
Explanation: The cornea has no blood vessels so that it remains completely transparent and does not interfere with vision. Because of this, it receives oxygen directly from the air, mainly through the tear film (and partly from the aqueous humor).
In simple words: Since there are no blood vessels in the cornea, it takes oxygen directly from the air instead of blood.
✅ Exam Tip: In MCQs, options may include Lungs, Skin, Heart, and Cornea — the correct answer is Cornea.
