What are two primary functions of the kidney?

I had a kidney stone issue last year, so I read a lot about this. Basically, they clean your blood by removing toxins through urine, and they also control your body's water levels so you don't get dehydrated or bloated.

Hey, don't stress too much about the biology terms! Simply put, kidneys act like your body's personal water filter, throwing out all the waste and keeping your blood pressure and fluid levels in check. Just drink enough water daily to keep them happy!

Since I love spicy street food, I always appreciate my kidneys! Their first job is filtering out all the excess sodium and waste from what we eat, and the second is maintaining the perfect water balance so we don't feel swollen after a heavy salty meal.

To put it practically, kidneys perform two vital roles: excretion of waste products like urea and creatinine, and regulation of electrolytes and fluid balance in our system. Keeping them healthy just requires staying hydrated and avoiding excessive painkillers.

I am just starting to learn about kidney health because my uncle has some issues. I read that they filter blood and help in producing red blood cells too, is that correct? It seems like they do so many things behind the scenes.

My elders always tell me to drink barley water for kidneys, but doctors say the real science is that they filter metabolic waste and regulate blood pressure. It is amazing how these small organs do so much heavy lifting for our body's chemistry daily.
