1) What is Dialysis?

• Dialysis is an artificial method to purify blood in case of kidney failure.
• It is done using an artificial machine which functions like a kidney.
• The frequency of the dialysis depends on an individual's age, diet and medical condition.

2) Name the Blood Vessels Which Carry Blood to the Kidneys.

• Renal veins and arteries carry blood to the kidneys.
• The renal artery carries the unfiltered blood from body parts to the kidneys for filtration.
• The blood, once filtered, is sent back to the body parts with the help of the renal vein.

3) How Does the Weakening of Bones Be Related to Kidney Diseases?

• Kidneys play a vital role in keeping the level of phosphorus balanced in our bodies.
• A balanced phosphorus level is necessary for balancing Vitamin D in our body. Vitamin D is essential for the absorption of calcium in the body.
• An increase in phosphorus levels does not allow calcium to get absorbed into the body, leading to weakening bones.

4) Explain How Kidney Stones Are Formed.

• An increase in the concentration of uric acid and calcium salts in the blood may lead to the formation of kidney stones.
• This is because the kidney cannot filter these substances efficiently when their level increases, and they start depositing inside the kidneys in the form of kidney stones.
