Organs function by your Autonomic nervous system which is responsible for things that you can’t control. Heart rate, digestion, reproductive functions, etc. And even takes over breathing when you choose not to control that.

Basic bodily functions like breathing and heart beat are plain hardwired in to your body. Just like simple electrical circuits. Yes, there are things (hormones) that can regulate them up or down, and your concious brain can override the signals. But evolution has conserved this feature because it is so efficient at keeping animals alive.

Your heart beat for example is controlled by the “sino-artial node”. It is basically an electrical timer that self regulates it’s electrical pulses, and doesn’t even need input from your brain to keep your heart going (hence why you can be brain dead, but still “alive”).

For a lot of things, it doesn’t. Ever see a baby try feed themselves a Cheerio? At first their movements are jerky and uncoordinated. They are lucky if they get the thing near their mouth, let alone in it. As they practice, the brain develops and improves control over gross motor skills and eventually fine motor skills. Before you know it, that they can pick up dozens Cheerios, get them in their mouths, and pester you for more before you can even get the box put away.
