👉 The term "membranophone" is a colloquial term used to describe the process by which an organ, such as the lungs or heart, becomes inflamed with mucus. This mucus can cause discomfort and may also contribute to coughing. The term comes from the fact that the membranes surrounding these organs are lined with cells called "membranes," which contain mucous, and this mucus is what creates the mucus in the lungs.
