According to the equation of continuity, which states that the product of cross-sectional area and velocity is constant, as the cross-sectional area increases, the velocity of blood flow decreases. This is because the same amount of blood must pass through a larger area, so the velocity decreases in order to maintain the same flow rate.

As the Total Cross-Sectional Area of the Vessels Increases,the Velocity
