Study Notes
Kidney Malfunction and Urea Accumulation
- Kidneys are responsible for filtering blood and removing waste, including urea.
- When kidney malfunction occurs, urea accumulates in the blood, leading to a condition known as uremia.
Urea Removal Methods
- Urea can be removed from the blood in patients with kidney malfunction through dialysis.
- The unit used for this process is referred to as an artificial kidney or dialyzer.
Hemodialysis Process
- During hemodialysis, anticoagulants are added to the blood drained from an artery to prevent clotting.
- The composition of the dialysing fluid includes electrolytes, glucose, and bicarbonate, which help balance blood chemistry during the process.
Mechanism of Filtration
- In the artificial kidney, the passage of molecules is facilitated by a semipermeable membrane, which allows for the movement of waste based on the concentration gradient.
Blood Return and Treatment
- The cleared blood is pumped back to the body using a blood pump.
- The ultimate method for correcting acute renal failures is often a kidney transplant.
Kidney Stone Formation
- The formation of insoluble masses of crystallized salts within the kidney is known as nephrolithiasis or kidney stones.
