肾藏象理论包括7个系统结构,即肾-精系统、肾-脑系统、肾-髓系统、肾-骨系统、肾-元气系统、肾-津液系统、肾-天癸-冲任系统。肾-精系统为肾藏象系统结构的核心,由先天之精(元精)、后天之精、脏腑之精和生殖之精等构成,通过肾精、肾气、肾阴、肾阳发挥生理功能活动;肾-脑系统由元精化生元神而成,体现在精舍志、在志为恐;肾-髓系统由骨髓、脊髓、脑髓构成,肾精生髓,髓化生血液,充养骨骼,汇聚脑脊;肾-骨系统是构成人体的框架,支撑人体、保护内脏和进行运动,齿为骨之余,骨、齿为生长壮老之外候;肾-元气系统突出"肾为元气之根",为生命活动之原动力,"肾主纳气"为呼吸运动的保证;肾-津液系统主司和调节全身津液代谢,与肾主气化、司开阖、为胃之关、合于膀胱密切相关;肾-天癸-冲任系统具有调控精血、繁衍生殖的作用,与女子胞及男性精室、睾丸等功能相关,肾藏象7个系统在人体生命活动中具有重要的调控作用。
