血液滲透壓的調解機制:(起因-低血容)step1:低血容→近絲球體器感應→刺激→近絲球體分泌reninstep2:angiotensinogen(肝製造)→renin刺激→angiotensin I(*angiotensin I沒有活性)step3:angiotensin I→angiotensin converting enzyme(肺臟內皮細胞製造)→angiotensin II (*angiotensin II 有活性)step4:angiotensin II→刺激→腎上腺皮質→分泌→aldosterone 醛固酮(鹽類皮質酮)→刺激→遠端腎小管再吸收Na+→高滲血→刺激→下視丘製造antidiuretic hormone(ADH) →刺激→腦下垂體後葉分泌antidiuretic hormone(ADH)(*antidiuretic hormone(ADH)是由下視丘製造,儲存於腦下垂體後葉)step5:ald...
