what's the difference between mucus and sputum hassam? :|

 

[hassam]

well mucus can refer to bodily fluids from different areas of body as well but phlegm or sputum only from lungs

 

[hassam]

for diagnosis of tuberculosis doctors are doing sputum stain test.....in which they view the sputum under microscope to see if mycobacteria is present or not
