If you want to learn more about the renal system, then urine the right place! Take a minute and imagine a dirty pool filled with algae. Placing a filter in this pool will cause the algae to be flushed out and disposed of, and after a time you’ll have a nice, clean, crispy blue pool to enjoy. Just like the filter for a pool, our kidneys filter our blood and remove toxic wastes from it. Humans have developed a system of disposing of this waste, while retaining nutrients and substances important to our well-being.
Our kidneys play a vital role in maintaining homeostasis, or the physiological balance of the body. Every thirty minutes, our kidneys filter the entire supply of blood in our body. Unfortunately, they are also prone to disease, which is illustrated by the fact that 1 in every 9 American adults currently has a kidney disease. Additionally, more than 82% of Americans waiting for a life-saving organ transplant is waiting for a kidney, but only 17% of these patients get one each year.
In this tutorial, learn how the kidneys take blood and very selectively extract waste from it to expel from the body as urine.
