Question

Which one of the following is synthesised in human body that dilates blood vessels and increases blood flow?

Accepted Answer

Nitric oxide (NO) is produced naturally by the human body and is one of the most important molecules for blood vessel health. It's a vasodilator, meaning it relaxes the inner muscles of your blood vessels, causing the vessels to widen. In this way, nitric oxide increases blood flow and lowers blood pressure. Hence option (a) is the correct answer.
