Which term describes a thin, watery discharge from the nose?

The term "rhinorrhea" specifically refers to a thin, watery discharge from the nasal passages. This condition is often associated with various medical scenarios, such as allergies, colds, or infections. The term emphasizes the nature and consistency of the discharge, indicating that it is not thick or purulent but rather clear and liquid-like.

In contrast, sputum refers to the mucus that is coughed up from the respiratory tract, often having a thicker consistency than rhinorrhea. Mucus is a more general term that describes a slippery secretion produced by, and covering, mucous membranes, and it can be thick or thin depending on the context. Exudate refers to fluid that accumulates in a cavity or tissue due to inflammation or infection, which can also be thicker and may contain cells or other substances, making it different from the clear, watery nature of rhinorrhea.
