Blood pressure is the force of blood against the artery walls circulate. Blood pressure in the arteries correlates directly with the amount of blood pumped by the heart and the amount of resistance in peripheral blood vessels, according to the http://vascuvite.com/blood-pressure-after-eating-empty-stomach/. Blood pressure is usually held in a narrow range to provide the optimal amount of blood to the tissues without damaging the vessel wall. Although many factors affect blood pressure, there are two main ways the body maintains blood pressure control.
– Central nerve system
The sympathetic nerve system gives a fast response to a decrease in blood pressure. Area of ??the aorta and carotid artery containing pressure-sensitive receptors that detect small changes in blood pressure. When the pressure drops, these receptors send signals to the brain stem. This hormone is then released from the adrenal gland, causing the heart to beat faster and stronger to pump blood.
Kidney, such as the aorta and carotid, contains receptors that respond to changes in pressure in the arteries. If the blood pressure drops too low, an enzyme called renin is released from the kidneys.
