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 an important structure within your respiratory system, which is the organ system that delivers oxygen to your bloodstream. The trachea is a rigid tube that conducts air from your larynx to your bronchi.The trachea's rigidity is maintained by a series of cartilaginous rings arranged along its length called C-shaped cartilage rings.hese cartilage rings are C-shaped to provide room for your esophagus, which lies along the backside of your trachea. The gaps between the cartilage rings are bridged by a tough elastic membrane. The trachea is very resistant to compression, but it is capable of stretching lengthwise.
