Glucagon

Growth hormone

Parathyroid

Thyroxine

Correct Answer: Option C

Explanation

1. In the human body, the regulation of blood calcium and phosphate levels is primarily managed by the Parathyroid hormone (PTH). 2. PTH is secreted by the parathyroid glands and increases blood calcium levels by stimulating bone resorption, increasing calcium reabsorption in the kidneys, and promoting the activation of Vitamin D, which enhances intestinal calcium absorption. It also promotes phosphate excretion by the kidneys.
