Which blood vessel play key role in regulating blood pressure?

Answer 1

There's a baroreceptor on the arch of the aorta that is sensitive to changes. Also there are baroreceptors in the carotid arteries. Both of these baroreceptors monitor the changes in mean arterial blood pressure.

Answer 2

3 years ago, I was diagnosed - hypertension with a reading of 160/100. I used to feel dizzy a lot, my legs had awful cramps, and levels were very low in my potassium, causing my fingers and toes to always cramp together. One day I started to feel really faint while I was driving with my daughter in the back seat and I passed out, hitting 3 cars and ending up in a ditch. That moment,I knew I had to do something because my meds weren't working. I heard about this diet from a friend and thought I'd give it a shot. The results have been remarkable. In just 21 days, I honestly can't remember feeling this good, my blood pressure went from 175/110 to 125/70.

Answer 3

If i had to pick one, i'd say the renal (kidney) blood vessels. There is a system which regulates your blood pressure, called the renin-angiotensin system. Angiotensinogen is released by the liver. When your blood pressure drops, your kidneys release renin, which change angiotensinogen to angiotensin I. angiotensin I then increases your blood pressure through some various physiological effects. Without renin from the renal blood vessels though, blood pressure could not be regulated. best of luck

Answer 4

It is very difficult to choose one single blood vessel, because all of the vessels in your body are linked. There is the arterial system, venous system, and of course your heart. All of these are sensitive to thousands of signals (chemical, physical, reflexive, etc) that regulate your blood pressure. Even gravity has an effect on your blood pressure. Total blood volume (amount of blood you have) will influence blood pressure. If you really need one example, the aorta, which is the largest artery in your body, is a very flexible artery that expands and contracts with sufficient force to spread blood to all parts of the body. The pressure in the aorta is therefore very important to maintain. I've attached a starter article below.

Answer 5

For the key role, you have something called baro-receptors located in your carotid arteries. They are sensitive to changes in pressure and increase it or decrease it as needed.
