The kidney GapFill

Water is lost from the body in a number of ways, including through sweating, which cannot be controlled. The only way the body can control the water balance of the body through the loss of water is via  hair lossurinationdialysisskin shedding. The organ primarily responsible for this is the  gallbladderheartkidneystomach. It filters the blood and  actively absorbsactively secretesdeselectively reabsorbsselectively reabsorbs the useful substances contained in the blood in a series of tubes called  an alveolusa nephrona mitochondriona ribosome. This structure has many parts, including:

• the Bowman's capsule, containing a network of capillaries called the   glomeruluspituitary glandarterioleurethra,
• two  selectedregulatedconvolutedanaerobic tubules which increase its surface area,
• and a permeable  renal veincollecting ductcortexrenal artery through which water passes immediately before entering the ureter.
