This MCAT Basics podcast covers three common hormone axes. I break down the hypothalamic-pituitary-adrenal (HPA) axis, the hypothalamic-pituitary-gonadal (HPG) axis, and the renin angiotensin-aldosterone System (RAAS) axis. I explain the anatomy of the regions, organs, and hormones involved, and detail the physiology within each axis.
