In an aneurysm, the cross-sectional area of a vessel expands. With the approximation that blood is non-viscous and incompressible, and that you have laminar flow, which one of the following is true in the expanded segment, compared to the normal vessel?
The flow is lower
The velocity is lower
The pressure is the same
The density of the blood increases
The velocity is higher
The pressure is lower
