Saliva is the watery substance produced in the mouth that helps with digestion and lubrication, while sputum is the mucus or phlegm that is coughed up from the respiratory tract. Saliva is mainly produced by salivary glands, while sputum is produced by the respiratory system in response to infection or irritation.
Phlegm is a sticky substance produced by the respiratory system to help trap and clear away germs and irritants.
To dispose of sputum, it should be collected in a tissue or disposable container and then sealed in a plastic bag before discarding it in a waste bin. It is important to wash hands thoroughly after handling sputum to prevent the spread of infection.
It typically takes about 2-3 days for a sputum culture to show positive results. However, the exact time can vary depending on the specific laboratory testing procedures and workload.
