    动物的内分泌系统通过激素的产生、分泌和调节来控制人体过程,激素是细胞和器官活动中的化学 “信使”,最终维持人体的稳态。 内分泌系统在生长、新陈代谢和性发育中起着作用。 在人类中,常见的内分泌系统疾病包括甲状腺疾病和糖尿病。 在经历变态的生物体中,变态过程由内分泌系统控制。 例如,从蝌琶到青蛙的转变是复杂而细微差别的,无法适应特定的环境和生态环境。

    照片 A 显示了一只蝌蚪。 照片 b 显示了一只青蛙,它已经长出了双腿,但仍有蝌蚪的尾巴。 照片 C 显示了一只完全长大的青蛙。
    \(\PageIndex{1}\):如图所示,两栖动物的变态过程是由荷尔蒙驱动的,如图所示。 (来源 “蝌蚪”:布莱恩·格拉特威克对作品的修改)
