Creating a Passphrase. A passphrase is simply a phrase or sentence that you use instead of a word or set of characters. Most password systems don't allow the space character, so you'll typically capitalize the first letter of each word instead.
The blood is passed through the structure of the kidneys called nephrons, where waste products and excess water pass out of the blood stream.     *Basically*     The kidneys regulate the body's fluid volume, mineral composition and acidity by excreting and reabsorbing water and inorganic electrolytes.
How do the kidneys work? The kidney is not one large filter. Each kidney is made up of about a million filtering units called nephrons. Each nephron filters a small amount of blood. The nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process.
