The digestive system, often romanticized as the body's second brain, does far more than just process food. At its core lies an elegant, multilayered structure that not only drives nutrient absorption and metabolic efficiency but also plays a surprising role in mental well-being. Understanding the intricate architecture of the gastrointestinal (GI) tract, including each of the distinct layers of the digestive system, opens a gateway to decoding how disruptions in gut physiology can ripple outward to influence psychological health. In recent years, a surge in research connecting the gut-brain axis to various psychiatric conditions has renewed scientific interest in gut structure, composition, and functionality. This article dives deep into the layers of gut anatomy and physiology, examining how their integrity shapes both gastrointestinal and mental health outcomes
