🧠 Explanation:
Hemodialysis is a medical process used to filter and purify the blood of individuals whose kidneys are not functioning properly. It involves removing waste products, excess salts, and fluids from the bloodstream through a dialysis machine and a special filter called a dialyzer. This treatment helps maintain the body’s chemical balance and prevents the buildup of harmful toxins. Hemodialysis is commonly used for patients with chronic kidney disease or acute kidney failure. The procedure is life-saving, often performed multiple times a week, and plays a critical role in sustaining the health and well-being of patients awaiting kidney transplants or managing long-term renal issues.
