Understanding Kidney and Liver Function
Kidney Function
The kidneys filter blood, remove waste, balance electrolytes, regulate blood pressure, and produce urine. They also help in:
- Removing toxins and excess minerals
- Producing hormones like erythropoietin (for red blood cell production)
- Maintaining fluid balance
