The pressure difference between the base of the aorta and the right atrium is the?

circulatory pressure


Pressure in the aorta is greatest during what?

The pressure in the aorta is greatest during ventricular systole, which is when the heart contracts and pumps blood into the aorta. This creates a surge in pressure that is known as systolic blood pressure.


Coronary perfusion pressure?

the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.


Where is blood pressure the highest?

Aorta


Does the aorta have the lowest blood pressure?

no!


Why does blood pressure in aorta decrease further form heart?

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.


Pressure in the aorta will be greatest during?

"systole"


Why must a pressure difference exist between the aorta and the vena cavae?

Pressure must move from one area to another, otherwise no flow will occur. In the case of the human heart, pressure pushes blood from the aorta, through arteries, arterioles, capillaries, venuoles, and finally veins, to the vena cavae, where the blood goes back into the heart to be re-oxygenated.


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.


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 is blood pressure is the greatest?

in the arteries


What has a higher blood pressure the aorta or vena cava?

The arterial system generally has a higher pressure than the venous system, so the answer is the aorta. Pressure is lost when the arteries split into capillaries, which have leaky walls.
