Why Many Parasites Prefer Low-Oxygen Zones Parasites don’t just hide randomly in the body. Many have adapted to thrive in low-oxygen zones , such as the gut lumen, deeper tissue layers, or stagnant lymphatic areas. These environments provide relative safety, as immune surveillance and detox signaling are often weaker. A key survival strategy for these organisms is anaerobic metabolism . In low-oxygen conditions, parasites switch from typical oxygen-dependent energy pathways t
