👉 Pleurogenous refers to a type of organism that lives in the membrane-bound cavities or spaces within other organisms. These structures are known as pleura, which is the membrane covering the lungs and chest cavity. Pleurogenuses play important roles in the respiratory system by filtering air, removing mucus and debris, and providing structural support for the lungs. They also help regulate temperature and humidity in the body, acting as a barrier to pathogens and maintaining homeostasis.
