As the blood moves through the aorta, the friction of the walls of the aorta decreases velocity. This velocity decrease results in a decrease in pressure.

Do arteries get smaller as they move further from the heart?
The blood pressure in the arteries will decrease as they move further away from the heart. The arteries are the vessels which regulate the blood pressure from the heart.Ê
Where is blood pressure the highest?
Aorta
Does the aorta have the lowest blood pressure?
no!
Is blood pressure highest in the aorta pulmonary artery capillary bed or subclavian vein?
The order, from most to least pressure: * Aorta * pulmonary artery * capillary bed * subclavian vein This is because the aorta takes blood the farthest distance, from the heart to the rest of our body organs, so it requires a greater push from the heart. Pressure in the veins is always lower, due to the fact the blood flowing through them has travelled further. The pulmonary artery doesn't take blood as far as the aorta, so it therefore does not need as high a pressure.
How would relaxing the smooth muscles in arteries affect blood pressure?
Blood pressure would decrease
Do arteries hold blood at high pressure?
To put it simply: YES. The blood in the arteries is at a higher pressure than the blood in the veins. This is because it has just come from the heart. As you get further along the blood vessels, blood pressure will decrease. This is due to several reasons. Friction will increase as the blood hits the vessel walls, bends and splitting of the vessels will disrupt the blood flow, and the volume of vessels will increase (the total combined volume all the capillaries is greater than that of the aorta).
Where is the blood under the most pressure?
Blood is under the most pressure in the aorta- the largest artery in the body originating fro the left ventricle of the heart.
Where do you have the highest blood pressure?
aorta. The left ventricle pumps the blood into it...
Which blood vessels can withstand high blood pressure?
Ascending Aorta
In which kind of blood vessels is blood pressure usually highest?
The arteries, but to be exact, the aorta.
Where is blood pressure is the greatest?
in the arteries
Why is the aorta so thick-walled?
this is because, due to high thickness of left ventricle blood gets into the aorta with high pressure, and if the aortic wall is not thick, high blood pressure in aorta breaks open wall.
