Dialysate
Dialysate
Dialysate (/daɪˈælɪseɪt/), also known as dialysis fluid, is a chemical solution used in dialysis to remove waste products and excess fluids from the blood when the kidneys are not able to perform this function adequately.
Etymology
The term "dialysate" is derived from the Greek word dialysis, which means "dissolution". It refers to the solution that dissolves waste products during the dialysis process.
Composition
Dialysate is composed of purified water, electrolytes, and a buffer. The electrolytes typically include sodium, potassium, calcium, magnesium, and chloride. The buffer is usually bicarbonate, which helps to maintain the pH of the blood during dialysis.
Function
The primary function of dialysate is to help remove waste products from the blood during dialysis. It does this by creating a concentration gradient between the blood and the dialysate. This allows waste products and excess fluids to move from the blood, across the dialysis membrane, and into the dialysate.
