Translation of "systemic" into Chinese

In the systemic circulation, your body’s microscopic “trucks,” the red cells, set out from the heart to the body tissues.

在体循环 内,你体内的微型“货车”,即红血球,会由心脏出发,并且走遍全身的器官组织。

I'm sure it wouldn't be too hard to find out who hacked into our system.

要找出入侵我们系统的黑客,我相信不会太难。
