The HPA Axis is essentially the endocrine system's companion to the sympathetic nervous system.

HPA 轴本质上是内分泌系统与交感神经系统的伴侣。

Today we looked at the endocrine system, and how it uses glands to produce hormones.

今天我们研究了内分泌系统，以及它如何利用腺体产生荷尔蒙。

People with a family history of some cancers or genetic problems with the endocrine system should not take such drugs.

有某些癌症家族史或内分泌系统遗传问题的人不应服用此类药物。

Alright, as a quick recap, your pancreas produces both hormones for the endocrine system and digestive enzymes for the exocrine system.

好！快速回顾下：胰腺产生内分泌系统所需的2种激素胰岛素和胰高血糖素，以及外分泌系统所需的消化酶。

The endocrine system is made up of chemicals called hormones.

内分泌系统由称为激素的化学物质组成。

The endocrine system acts on neurons in the brain, which controls glands in the brain, which sends signals to other glands to tell them to make more or less hormone.

内分泌系统作用于大脑中的神经元，神经元控制大脑中的腺体，腺体向其他腺体发送信号，告诉它们制造更多或更少的激素。

The endocrine system produces hormones that are instrumental in maintaining homeostasis and regulating reproduction and development.

内分泌系统产生的激素具有维持稳态，调节生殖和发育的作用。

All of these hormone messengers and the tissues that make them, control them, and shuttle them throughout the body are known as the endocrine system.

所有这些激素信使以及制造它们、控制它们并将它们穿梭于全身的组织都被称为内分泌系统。

The endocrine system. The two systems that control body activities are the endocrine system and the nervous system.

前者通过一种叫做激素的化学信使来发挥控制作用。激素由多种内分泌腺体产生，它们将激素直接释放进入血中。

Behind the scenes, the endocrine system works constantly to orchestrate these changes.

在幕后，内分泌系统不断地协调这些变化。

The endocrine system regulates its hormones through negative feedback, except in very specific cases like childbirth.

内分泌系统通过负反馈来调节激素水平，只有在非常特殊的情况下，如分娩时，才会例外。

But chemicals that target the endocrine system have been known to break that rule.

但众所周知，针对内分泌系统的化学物质会打破这一规则。

They are not considered a part of the endocrine system.

它们不被认为是内分泌系统的一部分。

The collection of endocrine glands makes up the endocrine system.

内分泌腺集合起来构成内分泌系统。

The endocrine system relies on interactions between three features to do its job: glands, hormones, and trillions of cell receptors.

内分泌系统依靠三种功能之间的相互作用来完成其工作：腺体、激素和数万亿个细胞受体。

An enduring misconception around the endocrine system is that there are exclusively male and female hormones.

围绕内分泌系统的一个长期误解是，只有男性和女性荷尔蒙。

The primary function of the endocrine system is to regulate our bodily processes, not control us.

内分泌系统的主要功能是调节我们的身体过程，而不是控制我们。

OK, to begin to understand our hormones — and the endocrine system that produces, releases, and re-absorbs them — we have to step back and take a broad view.

好吧，为了开始理解我们的荷尔蒙——以及产生、释放和重新吸收荷尔蒙的内分泌系统——我们必须退后一步，从更广阔的角度来看。

But most of the time, the endocrine system manages to keep our bodies in a state of balance.

但大多数时候，内分泌系统设法使我们的身体保持平衡。

The endocrine system also includes a few organs — like the gonads, the pancreas, and the placenta in pregnant women — all of which have some other non-hormonal functions and are made up of multiple tissue types.

内分泌系统还包括一些器官——比如性腺、胰腺和孕妇的胎盘——所有这些器官都有一些其他的非激素功能，并且由多种组织类型组成。
