Question

Dialysis is used for people with defective kidneys. It involves the process of :
1. adsorption
2. osmosis
3. electrophoresis
4. diffusion
5.

Answer 1

Correct Answer - Option 2 : osmosis

The correct answer is osmosis.

• Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly.
• Osmosis is the process by which solvent molecules pass from a solution of lower concentration to a solution of higher concentration through a semipermeable membrane.

• Kidney:
• Kidneys are bean-shaped organs located on either side of the spine, below the ribs, and behind your belly.
• The left side kidney is placed a little higher than the right side kidney.
• Kidneys are the excretory organs. 
• Each human adult kidney has a length of 10-12 cm, a width of 5-7 cm, and weighs around 120-170g.
• The function of the kidneys is to filter your blood.
• The kidney removes wastes, controls the body's fluid balance, and keeps the right levels of electrolytes.
• All of the blood in your body passes through them about 40 times a day.
• Renal Vein is the blood vessel which carries blood to the kidney.
• The cup-shaped part of the nephron is called the Bowman's Capsule.
• Uremia is a condition in which both kidneys fail to function.
• Kidney stones are generally calcium oxalate crystals.
• The volume of urine produced in an adult human being every 24 hours - 1.5 liters.
• The first organ transplant in the world - Kidney.
• The first kidney transplant in the world was conducted by - Dr. Joseph Murray.
• The functional unit of the kidney - Nephron.
• The study of kidneys is called Nephrology.

 

• Diffusion
  • Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.
• ​Adsorption
  • Adsorption is the process by which ions, atoms, or molecules adhere to the surface of a solid material.
• Electrophoresis
  • Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field.
