As blood pressure gives way to a number of complications, it is important to regulate it. It regulates the level of metabolites and electrolytes The useful substances like glucose, amino acids, salts and a major amount of water are selectively reabsorbed by the tubular part of nephron.. Nephron also helps in the maintenance of blood pH. Glomerulus filters the blood passing through it. In the glomerulus, blood plasma and dissolved substances (smaller than most proteins) get filtered into the glomerular capsule It also ensures to remove only harmful substances from the body that includes nitrogenous materials.
