    The endocrine system. The two systems that control body activities are the endocrine system and the nervous system. The former exerts its control by means of chemical messengers called hormones. Hormones are produced by a variety of endocrine glands腺体, which release the hormones directly into the blood stream.

内分泌系统。控制机体活动的两个系统是内分泌系统和神经系统。前者依靠其化学信使——激素发挥作用。各种内分泌腺体制造产生激素,并将激素直接释放于血流中。

A major gland is the pituitary脑垂体, which is located under the brain in the middle of the head. It produces at least eight hormones, which affect growth, kidney function, and development of the sex organs. Because some of the pituitary’s hormones stimulate other glands to produce their own hormones, the pituitary is called the master gland.

脑垂体是一个主要的腺体,位于头中部脑下方。它至少分泌八种激素,影响着人体的生长,肾脏功能和性器官的发育。由于脑垂体分泌的一些激素促进其它腺体分泌其激素,所以脑垂体是主要腺体。

Another gland, the thyroid甲状腺, is located between the collar bones锁骨. Its hormone controls the rate of the body’s metabolism. The sex organs(ovaries卵巢 and testes睾丸) make the sex cells and also make hormones that control certain characteristics of males and females. Located on top of each kidney is the adrenal gland肾上腺, which produces cortisone可的松 and adrenaline肾上腺素. The pancreas produces not only digestive enzymes but also insulin胰岛素 and glucagon高血糖素, which control the body’s use of sugar and starches淀粉.

另一个腺体,甲状腺,位于锁骨之间。甲状腺激素调控着人体新陈代谢的速度。性器官(卵巢和睾丸)分泌性细胞和性激素,这些激素控制着男性和女性的某些特征。位于每个肾脏上方的是肾上腺,它分泌可的松和肾上腺素。胰腺不仅分泌消化酶,同时也分泌胰岛素和高血糖素,这两种激素控制机体的糖分及淀粉的消耗。
