Beets are rich in nitrate, which in the body, converts to nitrite then becomes nitric oxide in the blood. Nitrite oxide is a gas that widens blood vessels and aids blood flow.

Baroreflex Regulation of Blood Pressure, Animation.

Baroreflex, or baroreceptor reflex, is one of the mechanisms the body uses to maintain stable blood pressure levels or homeostasis. Baroreflex is a rapid negative feedback loop in which an elevated blood pressure causes heart rate and blood pressure to decrease. Reversely, a decrease in blood pressure leads to an increased heart rate, returning blood pressure to normal levels. The […]
