Verified step by step guidance

Identify the hormone secreted by the parathyroid glands, which is parathyroid hormone (PTH).

Understand the role of parathyroid hormone (PTH) in the body. It primarily regulates calcium levels in the blood.

Learn how PTH increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium.

Recognize that PTH also increases calcium reabsorption in the kidneys and promotes the activation of vitamin D in the kidneys, which enhances calcium absorption in the intestines.

Conclude that the primary function of the hormone secreted by the parathyroid glands is to regulate calcium levels in the blood, not to regulate blood glucose levels, stimulate red blood cell production, or control metabolic rate.
