Q & A about Kidney

Q: What is the function of Renal Pelvis

A: Renal pelvis function as funnel, collecting the urine produced in the kidney and leading to ureter.

Q: What causes damage to kidneys?

A: They are diabetes (also called Type 2, or adult onset diabetes),  high blood pressure, infections, kidney stones and inherited diseases such as polycystic kidney disease.

Q: How does kidney work?

A: Kidneys work by 3 steps (Urinary process). These steps occur in Nephrons (inside part of renal phyramid). The steps are 1) Filtration, 2) Reabsorption, 3) Augmentation.

1) Filtration

Blood flows inside glomerulus. All small volume solutes, such as urea, uric acid, amino acids, hormones, glucose, ions, vitamins and water are filtered out and enter the Bowman’s capsule. The product of this filtration process is called glomerular filtrate. Its volume is 125 ml/min (180 liters/day).

2) Reabsroption

The glomerular filtrate then passes into proximal tubule. What are they reabsorb? They reabsorb all the usefull components, such as glucose, amino acids, vitamin C, calcium, potassium, sodium, chloride, bicarbonate and water (75%).

3) Augmentation

This step occur in distal tubule. It removes all the waster product from blood, such as urea, uric acid, creatinine.
