Study Notes
Renal Physiology Basics
- The kidneys filter approximately 200 liters of fluid from the bloodstream daily.
- Only a small percentage of the filtered fluid (less than 1%) leaves the body as urine, which is around 1.5 liters.
- The remaining filtered fluid returns to the circulation, allowing the body to retain essential substances.
- The primary function of the kidneys is to remove toxins, metabolic wastes, and excess ions from the body through urine while reabsorbing necessary substances into the blood.
