下丘脑—垂体轴如何协调全身激素？
How does the hypothalamic-pituitary axis coordinate hormones?
下丘脑释放调控激素指挥垂体，垂体再分泌促激素作用于甲状腺、肾上腺、性腺等靶腺，形成层层放大的内分泌指挥链。
The hypothalamus releases controlling hormones to the pituitary, which then secretes tropic hormones acting on target glands like the thyroid, adrenals, and gonads—a layered endocrine command chain.

甲状腺激素对身体的主要作用是什么？
What is the main role of thyroid hormones in the body?
甲状腺激素调控基础代谢率、体温和生长发育，分泌过少会怕冷乏力、过多会心悸消瘦，需维持精细平衡。
Thyroid hormones set basal metabolic rate, body temperature, and growth; too little causes cold and fatigue, too much causes palpitations and weight loss, requiring fine balance.

胰岛素是怎样调节血糖的？
How does insulin regulate blood sugar?
进食后血糖升高，胰腺释放胰岛素，促使肌肉和脂肪细胞摄取葡萄糖、肝脏合成糖原，使血糖回到正常水平。
After meals blood sugar rises, the pancreas releases insulin, prompting muscle and fat cells to take up glucose and the liver to store glycogen, bringing sugar back to normal.
