When an artery gets a constricted region due to plaque,how does the pressure in this region compare to the pressure in an unconstricted region adjacent?
A)Since this is a closed system,the pressure is the same in both regions.
B)In the constricted region the blood moves at a higher speed than in the unconstricted region resulting in an increased pressure.
C)In the constricted region the blood moves at a higher speed than in the unconstricted region resulting in a decreased pressure.
D)In the constricted region the blood moves at a lower speed than in the unconstricted region resulting in an increased pressure.

According to Bernoulli's principle, when the velocity of a fluid increases, its pressure decreases. In the constricted region of an artery, blood moves at a higher speed compared to the unconstricted region, leading to a decrease in pressure.
