Parathyroid hormone (PTH) increases osteoclast activity, which breaks down bone tissue and releases calcium ions into the bloodstream. This helps regulate calcium levels in the body. Thyroxine, calcitonin, and estrogen also play a role in bone health but do not directly increase osteoclast activity.
