Answer:
The kidneys are the filtering devices of blood. The kidneys remove waste products from metabolism such as urea, uric acid, and creatinine by producing and secreting urine. Urine may also contain sulfate and phenol waste and excess sodium, potassium, and chloride ions. The kidneys help maintain homeostasis by regulating the concentration and volume of body fluids. For example, the amount of H+ and HCO3 - secreted by the kidneys controls the body's pH.

I'd spent months hiking with friends to make sure I was in shape and, at the start, hustled to keep pace with our teenagers as we hauled ourselves up the steep boulders. But within a couple of hours I was straggling; they leapt past me like giddy mountain goats while I carefully picked my way up the rocks.
Was I disappointed? Actually, no. I felt smart. My 40-something body was telling me how to protect it from injury—and my hips and feet thanked me later. It turns out that our bodies routinely transmit this evolving wisdom, gently steering us away from activities or indulgences we can no longer tolerate to ones that will ensure continued good health.
Here are six other things your body's trying to tell you.
