S12E02 Walking Tall

The body has approximately 11 organ systems, all doing different things at the same time. In order to keep us functioning or well alive, they need one voice--a leader, a master. And in our brains that job belongs to the pituitary gland. It senses the body’s needs before they even arise, working nonstop. The pituitary gland communicates with all of the other glands telling them when to produce the vital hormones we need to function. It keeps everything running smoothly, in perfect order. There’s no denying it--it has toughest job in the place. 人体大约有十一种器官系统，同时负责不同的功能，为了使人体正常运转或者说让人活着，它们就需要听从由领导或主人发出的指令，对大脑来说，发出指令的是脑垂体腺，它甚至能在身体察觉之前感知其需求，并持续作用。脑垂体腺会向其他腺体传达信息并告诉它们何时分泌维持生命所需的荷尔蒙，它使一切顺利运转有序进行。必须承认，它的任务最为艰巨。 Without a strong leader the whole machine’s out of whack. But it’s pretty simple--If the brain’s working, the body will listen. Your limbs want to hold you up. Your lungs want to breath. Your heart wants to beat. But none of them are any good without the brain. The brain keeps everything all together. Like a boss. 没有强有力的领导人，一切都会大乱，但这很简单。如果大脑运转正常，身体就会跟着一起走，你的肢体会支撑你；你的肺部会呼吸；你的心脏会跳动。但没有大脑，这一切都无用。大脑让一切运作，就像个老大一样。
