Question

Quizplus · Accepted Answer

Parathyroid hormone (PTH) and vitamin D work together to increase blood calcium levels. PTH stimulates bone resorption, releasing calcium into the bloodstream, while vitamin D increases calcium absorption from dietary sources in the intestine. Additionally, vitamin D increases calcium reabsorption in the kidneys. Therefore, PTH and vitamin D work in opposition to other hormones, such as calcitonin, which decreases blood calcium levels.
