Basically, a nephron comprises a renal tubule and blood vessels. The renal tubule expands into a cup-shaped structure called the Bowman's Capsule, which contains a ball of capillaries known as the Glomerulus. The Glomerulus is the primary structure of the filtering process.
Following glomerular filtration, the bulk of solutes are reabsorbed in the proximal tubule to prevent excessive losses of vital metabolites. In this nephron segment, reabsorption is largely active via dedicated transporters.
