众所周知,人体内的两个肾脏是产生尿液的脏器,有人称它是一对十分出色的“过滤器”,因为它们能将血液中的新陈代谢废物滤入尿中排出体外。肾脏在过滤血液制造尿液的过程中,还具有浓缩与稀释尿液的作用,而这种作用又是受内分泌腺——脑垂体所分泌的一种叫“抗利尿激素”所操纵的。当大量饮水时,脑垂体随即减少“抗利尿激素”的分泌,尿液便稀释;相反,当身体缺水时,“抗利尿激素”分泌增加,尿液便浓缩,浓缩的尿液颜色会加深而是浓茶状。
As we all know, the two kidneys in the body are the organs that produce urine. Some people call it a very good “filter” because they filter the blood’s metabolic waste into the urine and excrete it. The kidneys also have the effect of concentrating and diluting urine in the process of filtering blood to make urine, which is manipulated by the endocrine gland-secreted pituitary called “vasopressin.” When a large amount of drinking water, the pituitary gland immediately reduce the secretion of “antidiuretic hormone”, the urine will be diluted; the contrary, when the body is dehydrated, “antidiuretic hormone” secretion increased, urine will be concentrated, concentrated urine color will deepen But strong tea-like.
