Verified step by step guidance

Identify the function of each hormone listed in the problem. Thyroxine is primarily involved in regulating metabolism. Adrenaline is responsible for the 'fight or flight' response, increasing heart rate and energy availability. Insulin regulates blood glucose levels.

Understand the role of parathyroid hormone (PTH) in the body. PTH is crucial for maintaining calcium homeostasis. It increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium, enhancing calcium reabsorption in the kidneys, and activating vitamin D to increase intestinal absorption of calcium.

Recognize that calcium regulation is essential for various physiological processes, including muscle contraction, nerve function, and blood clotting.

Consider the source of each hormone. Parathyroid hormone is produced by the parathyroid glands, which are located behind the thyroid gland in the neck.

Conclude that among the hormones listed, parathyroid hormone is the one that directly regulates calcium levels in the body.
