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.
Filtration involves the transfer of soluble components, such as water and waste, from the blood into the glomerulus. Reabsorption involves the absorption of molecules, ions, and water that are necessary for the body to maintain homeostasis from the glomerular filtrate back into the blood.
