When blood flow in the arteries supplying the kidneys is completely blocked, the entire kidney or a portion of the kidney supplied by that artery dies (kidney infarction). Kidney infarction can lead to the inability of the kidneys to process and excrete the body's waste products (kidney failure). Blood vessel disorders of the kidneys have a number of causes, including blockages in the renal arteries or veins, inflammation of blood vessels , injury to the kidneys or blood vessels, and other disorders.
Iditarod veteran Kelly Maixner, of Big Lake, Alaska, leaves Nenana, Alaska on Monday, March 9, 2015. Nenana is the first checkpoint in the 2015 Iditarod and is about 60 river miles from the start in Fairbanks, Alaska. The Iditarod is a nearly 1,000-mile race that usually runs from Willow, Alaska to Nome, Alaska.
Not by chance, the Seward to Nome Trail as the Iditarod was originally called, was first mapped and marked in 1908 by a four-person Alaska Road Commission crew supported by dog teams.
