概括

在冠状动脉旁路移植中,端到侧的缩可以导致由于狭窄而导致移植失败. 计算流体动力学显示,75%的狭窄风险是内脏增生,而<50%的狭窄显示可接受的血液动力学.

Applications of Integration to Find Blood Flow

Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...
