It causes a change in brain and organ functions and ultimately in our behavior.

它使大脑和器官功能发生变化，最终导致我们的行为发生变化。

And just like in our bodies, different tissues work together to make organs function.

就像我们的身体一样，不同的组织一起工作，使器官发挥作用。

There's tremendous potential to use bioprinting to save lives and advance our understanding of how our organs function in the first place.

生物打印具有极大的潜能，它可以用来拯救生命，以及提高我们对器官运作的了解。

Also, some wouldn't be able to lift the machines that keep organs functioning, and special coolers will have to be developed to safely transport them.

另外，有些无人机无法携带维持器官运转的机器，因此必须研制特殊的冷却器才能安全地运输它们。

In darkness, our bodies produce a hormone called " melatonin" that helps us sleep, boosts our immune system, and helps a bunch of organs function.

在黑暗中，我们的身体会产生一种叫做“褪黑激素”的激素，它可以帮助我们入睡、增强免疫系统并帮助一系列器官发挥作用。

That steady rhythm helps determine the body's flow of hormones, with the broader circadian system acting like a conductor that keeps your organs functioning in time with one another.

这个稳定的规律决定着身体荷尔蒙的分泌，而整个生物钟像是指挥员使得各个器官协调运作。

When rejection does take place though, symptoms often arise such as flu-like symptoms, pain around the transplant, a decrease in the transplanted organs function, and sometimes even a fever.

然而， 当排斥反应确实发生时，通常会出现症状，例如流感样症状、移植周围疼痛、移植器官功能下降，有时甚至发烧。

Central Nervous System The CNS represents the largest part of the nervous system. It regulates organ function, higher thought, and movement of the body. Together, with the PNS, it has a fundamental role in the control of behavior.

2、中枢神经系统 ；中枢神经系统是神系统最大的部分，它调节器官功能、高级思维和身体的运动，和PNS一起在控制行为方面具有重要作用。
