Calcitonin has an opposite effect, as it decreases the levels of calcium in the blood. Overall, PTH has a strong effect on the blood concentration of calcium, whereas calcitonin has a more moderate effect and is not critical in helping the body maintain normal blood calcium levels.
Calcitonin has opposite effects to those of PTH in bone andkidney. Finally, 1Î±,25-dihydroxy-Vitamin D stimulates calcium absorption in thegut, and has effects in bone and kidney as well.The key to calcium homeostasis is the amount of calcium absorbed in the gut.Thereare always some losses in the feces, urine, and in sweat.inally, 1Î±,25-dihydroxy-Vitamin D stimulates calcium absorption in thegut, and has effects in bone and kidney as well.The key to calcium homeostasis is the amount of calcium absorbed in the gut.
