This study presents a theoretical model of the human body as a continuous metabolic conduit, validated by clinical data on intestinal obstruction and fasting survival. We define a quantitative "Port Coupling Strength" (C) to characterize the life-death dependency between input and output ports. Furthermore, physiological mechanisms such as the nasal cycle are analyzed as active stabilization systems for bifurcated channels. This work integrates embryonic topology with mass flux conservation to propose a unified framework for understanding biological system continuity and dynamic traversability
