renal tubules

Renal tubules are small, tube-like structures in the kidney that process blood to create urine. Blood enters the kidneys, where useful substances like water, salts, and nutrients are absorbed back into the bloodstream through these tubules. Waste products and excess substances are left in the tubules, which then transport them to the bladder as urine. The renal tubules have different sections that help fine-tune this process, ensuring the body maintains proper fluid and electrolyte balance. Essentially, they act as the kidney’s filtering and adjusting system, playing a key role in waste removal and fluid regulation.
