Common Hormone Axes
Manage episode 432776296 series 2770060
In this episode, we'll explore three crucial hormone axes: the hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gonadal (HPG) axis, and the renin-angiotensin-aldosterone (RAAS) system. We'll decode the complex interplays among the hypothalamus, pituitary gland, and various peripheral organs, focusing on how these hormone systems regulate everything from stress responses and reproductive functions to blood pressure and fluid balance.
We'll break down the HPA axis and its pivotal role in stress response, featuring hormones like corticotropin-releasing hormone (CRH) and cortisol. Next, we’ll navigate through the HPG axis to understand the hormonal orchestration behind testosterone, estrogen, and progesterone production. Lastly, we’ll zero in on the RAAS system, demystifying its essential function in blood pressure regulation and electrolyte balance.
