Question

where is blood pressure the greatest?
a arteries
b arterioles
c capillaries
d veins
e all are the same.

Explanation:

Blood pressure is highest in arteries. Arteries carry blood away from the heart under high pressure generated by the heart's pumping action. Arterioles are smaller branches of arteries and have lower pressure than arteries. Capillaries have very low pressure as they are involved in exchange processes. Veins carry blood back to the heart and have the lowest pressure among these as they rely on skeletal muscle contractions and valves to return blood.

Answer:

A. Arteries
