求翻译：During normal activities of daily living ,ADH is secreted in small amounts into the blood stream to promote reabsorption of water by the renal tubules ,which leads to a decreased excretion of water by the kidneys. When ADH is secreted in large quantities ,vasoconstriction of the smooth muscles occurs, which ultimately 是什么意思？ 待解决

在日常生活的正常活动，ADH分泌少量促进肾小管由肾脏排泄的水下降，从而导致水的重吸收进入血液流。当ADH大量分泌，平滑肌收缩的发生，从而最终提升血压。 ADH的升压效应产生的仅是在正常生理范围的大剂量。 ADH的分泌是由多个反馈回路调节，其中包括血浆渗透压。下丘脑内的渗透压感受器，其功能是分泌ADH时，血浆渗透压isincreased。另一方面，稀释血浆抑制ADH分泌。第二反馈回路或刺激ADH分泌主要是量或拉伸受体位于左心房。这些受体被激活时，细胞外液量增加，当这一切发生的时候。 ADH分泌被抑制。在caroeid simus和主动脉弓压力感受器，位于第三反馈环路的受体。动脉血压下
