In the aorta,
A) the blood pressure and blood velocity are both high.
B) the velocity of blood flow is high, but blood pressure is low.
C) the resistance to blood flow is high, but velocity of blood flow is low.
D) the resistance to blood flow and the blood pressure are both low.
E) velocity is diminished because the total cross-sectional area is small.
Cross-Sectional Area
The area of a particular section of an object or substance that has been cut across its width, used to determine properties like resistance and strength.
Aorta
The body's biggest artery starts from the heart's left ventricle and stretches down to the abdomen, dividing into smaller arteries there.

Final Answer :
A
Explanation :
In the aorta, both the blood pressure and blood velocity are high. The aorta is the main artery leaving the heart, carrying oxygen-rich blood to the body, thus experiencing high pressure from the heart's pumping action and high velocity as blood is directed into systemic circulation.
