Homonym: Saline (Salt)
Saline is a solution that contains salt, specifically sodium chloride, dissolved in water. It is commonly used in medical settings for various purposes, such as hydration, wound cleaning, and as a vehicle for delivering medications. Saline solutions can come in different concentrations, with normal saline being a 0.9% solution, which is similar to the salt concentration found in the human body.
In addition to its medical uses, saline is also found in nature, such as in oceans and salt lakes, where it contributes to the overall salinity of the water. Saline solutions are also used in laboratories for experiments and in food preservation processes.
