An artery narrows such that its cross-sectional area is reduced by half.
If blood is treated as an ideal, incompressible fluid, what happens to the gauge pressure within the narrowed segment according to Bernoulli's principle?
- The pressure increases to maintain a constant flow rate.
- The pressure remains constant because the fluid is incompressible.
- The pressure increases because the fluid is more compressed in the narrow region.
- The pressure decreases because the fluid velocity increases.
