② In cold environment, sweat secreted by sweat glands decreases, so micturition increases;

③ The symptoms of diabetic patients are "three more and one less", that is, drinking more, eating more, urinating more and wasting away;

(4) antidiuretic hormone can promote the reabsorption of water by renal tubules and collecting ducts and reduce urine output;
