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.
The trachea is a flexible tube that extends from the larynx into the thorax. Its main function is to act as a conduit for air, but it also helps condition the inspired air. The trachea consists of four layers: a mucosa (epithelium and lamina propria), a submucosa, a fibrocartilage layer and an adventitia.
