What term describes mucous coughed up from the lungs?

Sputum is the material produced by the lower respiratory tract that is expelled by coughing. It specifically describes secretions from the lungs and airways, which is why it’s the correct term for mucous coughed up from the lungs. In clinical settings, sputum can be examined to assess infection or disease, and its characteristics (color, consistency, presence of blood) help guide diagnosis. Mucus is secreted by mucous membranes throughout the body, not necessarily from the lungs; phlegm is a non-technical, lay term for chest mucus but sputum is the precise clinical term for material expectorated from the lungs. Serum is the liquid part of blood, and a mucus membrane refers to the lining tissue, not the expelled material.
