What is the primary function of the pituitary gland?

The primary function of the pituitary gland is to regulate growth, which is primarily mediated through the secretion of growth hormone (GH). The pituitary gland is often referred to as the "master gland" of the endocrine system because it produces hormones that can influence other glands and regulate various physiological processes in the body. In addition to growth hormone, the pituitary gland releases several other hormones that play crucial roles in processes such as metabolism, reproduction, and stress response. Therefore, its critical role in promoting physical growth and development, especially during childhood and adolescence, underscores why regulating growth is considered its primary function.
