that the cardiovascular system uses to accomplish that.

所遵循的一些工程学原理
Then next week we'll talk about--

下周会讲到
we'll talk in some detail this Thursday about

本周四我们会精讲
how the heart generates the pressure that's needed to move the blood

心脏是如何产生血液运动所需压力的
and how you can create this flow

还有就是一个相对简单但却经久耐用的器官
with a relatively simple but durable machine, the heart.

即心脏是如何让血液流动起来的
Next Tuesday we'll talk about cardiac conduction electrophysiology,

周四我们会讲心脏传导的电生理学
how the heart regulates it's beating

心脏如何调节自身跳动
in order to generate orderly pattern of pressure generation.

从而产生有序的节律来生成血压
This is a cartoon of the cardiovascular system,

这是一幅关于心血管系统的画片
not showing the blood except by the colors here,

它并没有画出血液只是用不同颜色来指代
but showing the heart.

但画出了心脏
