Control Systems of the Body

Your body has two control systems fighting for dominance every single second. The nervous system

is like sending a text message, fast and direct to specific targets. But the endocrine

system? It's like dropping a bomb in your bloodstream that affects your entire body for

hours. Here's the wild part: steroid hormones like testosterone literally enter

your cells and rewrite your DNA instructions, while other hormones just knock on the door and trigger

a chain reaction inside. When you're stressed, your adrenal glands dump cortisol into

your blood, breaking down your muscles for emergency fuel. And get this: your

pituitary gland, smaller than a pea, controls almost every other hormone gland in your body.
