RTF full form in medical is Respiratory Tract Fluid, which is a type of fluid that is produced by the cells that line the respiratory tract. It helps to keep the airways moist and lubricated, which makes it easier for you to breathe. RTF also helps to protect the respiratory tract from infection by trapping and removing dirt, dust, and other foreign particles that you inhale. This is important because it helps to keep your respiratory tract healthy and functioning properly.
In healthy individuals, RTF is usually thin and clear. However, if you have an infection or inflammation in your respiratory tract, the amount or consistency of RTF may change. For example, if you have a cold or the flu, you may have more RTF in your airways and it may be thicker and more difficult to clear. In these cases, it’s important to drink plenty of fluids and rest to help your body recover and clear the excess RTF.
