Final answer:
The pituitary gland regulates body growth through the production of Growth Hormone.
Step-by-step explanation:
The endocrine gland that regulates body growth is the pituitary gland. The pituitary gland is often referred to as the master gland of the endocrine system, because most of the hormones it produces control other endocrine glands, including the thyroid gland, adrenal glands, and the gonads.
Growth hormone (GH), which is produced by the anterior pituitary, is particularly important for the control of the growth rate of muscle and bone. GH acts indirectly through insulin-like growth factors (IGFs).
