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.
The Nenana Canyon has great rapids for exciting raft trips. You can't see Denali from the entrance but if you drive to Mile 9 of the Park Road you may catch a glimpse of the mountain.. The Denali Visitor Center is about a mile down the Park Road just past the Roundabout. Denali Park is very exciting for kids 7 to 14 years old.
