This is the most simplified I could make it... Here’s a histology “slide” of a human adrenal gland for y’all who “don’t do cells.” (Placement may be a bit inaccurate, cause I stole this from a borrowed notebook.)
Fun fact: I once had someone try to argue with me that the adrenal gland is a “kidney warmer” that does not actually produce hormones, because “it doesn’t look like a real organ.”
