Answer 1

Answer:

Sputum is the thick mucus or phlegm that is expelled from the lower respiratory tract (bronchi and lungs) through coughing; it is not saliva or spit. Care must be taken in the sample collection process to ensure that the sample is from the lower airways and not from the upper respiratory tract.

Answer 2

If you're sick or the passages between your mouth and lungs get irritated by something such as smoke or air pollution, your body makes sputum. It's also known as phlegm. It's different from saliva, the thinner fluid your mouth makes to help you eat. When you cough, your body is trying to get rid of that phlegm.
