These carry it downward into the hollow organ known as the bladder.

然后它们将它注入一个中空的器官——膀胱。

The uterus is a hollow organ that sits behind the urinary bladder and in front of the rectum.

子宫是位于膀胱和直肠中间的空腔器官。

The urinary bladder is a hollow, muscular and distendible or elastic organ that sits on the pelvic floor.

膀胱是一个位于盆底的空腔、肌肉发达、可扩张或有弹性的器官。

It's these hollow organs that do the actual moving, digesting, and absorbing of food, and they include your mouth, pharynx, esophagus, stomach, and small and large intestines.

正是这些中空器官进行食物的实际移动、消化和吸收，它们包括你的嘴、咽、食道、胃和小肠和大肠。

In the case of norepinephrine, its effector is smooth muscle — the muscle that controls all of your involuntary functions of hollow organs, like the stomach, and bladder, and also your blood vessels.

就去甲肾上腺素而言，它的效应器是平滑肌——控制所有中空器官无意识功能的肌肉，比如胃、膀胱，还有你的血管。

Smooth muscles are used to control the flow of substances within the lumens of hollow organs, for examples, blood vessels and the alimentary canal, and are not consciously controlled.

平滑肌用于控制空腔器官内物质的流动，例如血管和消化道，并且不受意识控制。

Your body does not run on gasoline; instead, it relies on a pumping station known as your heart, which is a hollow organ that pumps blood through the blood vessels.

人体不依靠汽油运行； 取而代之的是，它依赖于称为心脏的泵站，这是一个空心的器官，可以通过血管泵送血液。

Blood travels through blood vessels, which are hollow tubes to carry blood, and blood is propelled by your heart, which is a hollow organ that pumps blood through the blood vessels.

血液流经血管（输送血液的空心管），血液是由心脏（中空的器官）推动的，将血液泵入血管。

Now, I'm quite sure that you're familiar with the key players here — they're the hollow organs that form the continuous tube that is your alimentary canal, aka the gastrointestinal tract, which runs from your mouth to your anus.

现在，我很确定你对这里的关键选手很熟悉——它们是形成连续管子的中空器官，也就是你的消化道，也就是胃肠道，从你的嘴延伸到你的肛门。
