WebThe role of. hormones. in renal function. Certain hormones and hormonelike substances are intimately related to renal function. Some of these, such as ADH (or vasopressin ), are produced outside the kidney and travel to the kidney via the blood as chemical messengers. Others are produced within the kidney and appear to exert only a local effect. WebBone serves as a vast reservoir of calcium. Stimulating net resorption of bone mineral releases calcium and phosphate into blood, and suppressing this effect allows calcium to be deposited in bone.
