Which term describes the thick drainage characterized by colors like green or yellow?

The term that describes thick drainage characterized by colors such as green or yellow is purulent drainage. This type of drainage typically indicates the presence of infection, as it consists of pus that contains dead white blood cells, bacteria, and tissue debris. The green or yellow coloration often results from the body's immune response to infection and the specific types of bacteria involved.

In clinical practice, recognition of purulent drainage is crucial as it typically requires further evaluation and may necessitate intervention, such as antibiotics or drainage of the infected area. Understanding the characteristics of different types of drainage is essential for effective patient assessment and management in various medical contexts.
