The wall of the aorta is highly elastic and so distends when the left ventricle contracts pumping blood into it. As the walls close back in they push the blood along in a more smooth fashion. This stops sudden pressure increases from bursting all the vessels.
Blood pressure receptors are found in the aorta (aortic baroreceptors) and carotid arteries (carotid sinus baroreceptors). These receptors detect changes in blood pressure and send signals to the brain to help regulate blood pressure.
To put it simply: The blood in the aorta has to go all around the body. Blood in the pulmonary trunk has to go all around the lungs. The body is, obviously, larger than the lungs. This means blood going around the body needs to be "pushed" more. This is because there is more resistance. For example, it's harder to push a car for 1 mile, then it is to push it 1 metre. Because the blood has to be pushed more, the heart (left ventricle) pumps it out at a higher pressure. Similarly, because the blood going around the lungs doesn't need to go so far, the heart (right ventricle) pumps it out at a lower pressure. Because the blood in the aorta is at higher pressure than the pulmonary trunk, it needs to have thicker walls. For example a fire hose is thicker than a garden hose because it needs to transport water at a higher pressure. The aorta contains large amount of smooth muscle and elastic tissue to help it cope with the high blood pressure.
There are many vitamins that can help lower blood pressure. Vitamins and minerals like Calcium, Magnesium, and Potassium can help with lowering your blood pressure. Adding more of these vitamins can help facilitate a blood pressure drop.
Baroreceptors are located in the walls of the aorta and carotid arteries, major blood vessels that carry blood away from the heart. They help regulate blood pressure by sensing changes in blood pressure and sending signals to the brain to adjust it accordingly.
Hi The pulmonary veins are responsible for carrying the oxygenated blood from the lungs to the left auricle. This blood is further pumps to the left ventricle that pumps the blood to the entire body with the help of aorta.
If you have this disorder you will have high blood pressure. If you are pregnant with high blood pressure this can be dangerous. Your doctor will help you lower your blood pressure.
They help regulate blood pressure (I think)
Yes, the wall of the pulmonary artery contains a layer of smooth muscle to deal with the high pressure from the heart, and to help push the blood along.
without blood pressure, blood would not be able to circulate throughout the body
The circulatory system which includes the heart and arteries carry oxygenated blood to the body cells.
