Which gland produces hormones that regulate metabolism, body heat, and bone growth?

The thyroid gland is essential for regulating metabolism, body heat, and bone growth because it produces critical hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones influence the rate of metabolic processes in the body, which includes how quickly or slowly the body uses energy. By controlling metabolic rate, the thyroid gland directly impacts body heat production since metabolism generates and regulates heat.

Moreover, thyroid hormones play a significant role in bone growth and development. They work in conjunction with other hormones, such as growth hormone and sex hormones, to ensure proper bone maturation and density. An imbalance in thyroid hormone levels can lead to various health issues, including growth disorders and changes in body temperature regulation.

The other glands mentioned have different primary functions. The adrenal gland is responsible for producing hormones related to stress response, including cortisol and adrenaline. The pituitary gland acts as the "master gland" that regulates other endocrine glands and produces hormones that affect growth, reproduction, and metabolism to some extent but does not directly produce the primary hormones for metabolism regulation. The hypothalamus is primarily involved in homeostatic functions and regulates various bodily functions, including temperature and hunger, but does not produce the hormones that primarily regulate metabolism and growth like
