There are three steps the kidney takes to form urine.  The first is glomerular filtration.  During this step, [blood] enters the capillary bed, called the [glomerulus], which acts as a filter.  There is a lot of pressure in this capillary bed because the diameter of the afferent arteriole is [bigger] than the diameter of the efferent arteriole.  Most of the blood moves into [bowmansspace] because of this high pressure and because there are [pores] between the capillary cells.  Some molecules remain in the blood, primarily those that are too [big].  Once fluid is in bowmans space, it is called [filtrate] Approximately [180] liters of this fluid are made per day, compared to 2-4 liters that are left in the blood capillary beds.
