As bone resorption fails while bone formation continues, excessive bone is formed. 14. This causes resorption of K + ions and secretion of H + ions. 15. As the aging process occurs, resorption exceeds formation. 16. Light weight bearing exercise tends to eliminate the negative effects of bone resorption . 17. Some people who experience increased bone resorption and decreased bone formation are astronauts. 18. In other countries is prescribed as a bone resorption inhibitor and antihypercalcemic agent. 19.
