Pancreas-specific lipase is measured with a test called Feline Pancreatic Lipase Immunoreactivity, known simply as fPLI. The test requires only a simple blood test. A fasting sample is preferred, but it is not essential for the accuracy of the test. Does the sample have to be sent away to a diagnostic laboratory?
A: The trachea is the tube in the throat that connects the mouth and nose to the lungs. It is also called a windpipe, and its function is to transport the air a person breathes in through his nose or mouth into the lungs. Without the trachea, the lungs do not receive oxygen, and humans cannot survive.
Trachea Conditions. 1  Tracheal stenosis: Inflammation in the trachea can lead to scarring and narrowing of the windpipe. 2  Tracheoesophageal fistula: An abnormal channel forms to connect the trachea and the esophagus. 3  Tracheal foreign body: An object is inhaled (aspirated) and lodges in the trachea or one of its branches.
