Which one of the following is synthesised in human body that dilates blood vessels and increases blood flow ?
A.Nitric oxide
D.Nitrogen pentoxide
C.Nitrogen dioxide
B.Nitrous oxide
Correct Answer: Option A
Nitric oxide (NO) is naturally synthesized by the human body and plays a crucial role in blood vessel health.
It functions as a vasodilator, which means it relaxes the inner muscles of blood vessels, causing them to widen.
By widening blood vessels, nitric oxide increases blood flow and lowers blood pressure.
Hence, option (a) is the correct answer.
