The kidney contains numerous performing units called Nephrons. Nephron is characterized by a filtering unit of small blood vessels that are connected to a tubule. When blood enters these filtering units, it is filtered and the outstanding fluid than gets passed through the tubule (Anon, 2013).
The adequate Chemicals and water are either increased or decreased from the filtered fluid according to the specific body's needs. The ultimatel product in this process is urine that human beings excrete. There is a huge role of Nephrons and glomerulus in the process of Kidney functioning.
