Lungs produce at least one hormone: Growth hormone-releasing hormone (GHRH).
While the hypothalamus is the primary source of GHRH, the lungs also produce it locally. GHRH's main functions include:
- Stimulating the release and secretion of growth hormone (GH) by the pituitary gland.
- Regulating the production of GH.
- Regulating hepatic insulin-like growth factor-1 (IGF-1).
