What Is the Function of the Glomerulus?

Glomeruli are the components that carry out the primary filtering action of the kidney. They connect on one side to the blood vessels that enter the kidney, and on the other side to fluid-collecting structures called tubules. The glomeruli accept the blood from the arteries and pass the filtered wastes and any extra water present into the tubules, according to the National Institute of Diabetes and Digestive and Kidney Diseases.
