3 身体部位及糖尿病中涉及到的激素

身体内葡萄糖的主要作用就如同燃料一样,但是葡萄糖也通过附着于蛋白质从而成为组织的能量来源。正常人(非糖尿病患者)的血糖浓度是非常有限的,身体也不会让血糖过高或过低,身体中的几个部位都参与到这个过程中。 有些部位参与的多些,比如肝脏,而有的则参与的少些,比如胰腺中的细胞。细胞是身体的最基本的组成机构,肉眼无法看到。在人体内有许多不同种类的细胞,其功能也是不同的。

荷尔蒙(激素)是由细胞产生的信号性物质,能够启动或停止身体过程。身体里有许许多多不同类型的激素,胰岛素就是其中的一个例子,由胰脏产生。你可能还听说过其他许多类型的激素,比如甲状腺、雄性激素、雌性激素。释放到血液里的激素以及被身体某些部位所吸收的激素叫做内分泌激素,由内分泌腺体产生。甲状腺激素、雄性激素、雌性激素都是内分泌激素的例子,分别由甲状腺体、睾丸和卵巢产生。你也可能听说过内分泌学家,实际上就是医生,主要治疗激素分泌紊乱的病人。
