Which body systems are primarily involved in the diagnosis of TCM pathologies?

The correct answer highlights the Zang and Fu organs, which form the core of Traditional Chinese Medicine (TCM) diagnostic principles. In TCM, the Zang organs (like the Heart, Liver, Spleen, Lung, and Kidney) are associated with yin, storing vital substances and regulating important physiological functions. The Fu organs (including the Small Intestine, Large Intestine, Gallbladder, and others) are primarily associated with yang, managing the digestion and transformation processes within the body.

When diagnosing pathologies in TCM, practitioners assess both the balance and interaction of these organs, considering how their functions are affected in health and disease. Each organ system is linked to specific emotions, physical symptoms, and even external environmental factors, making their understanding crucial for TCM diagnosis.

In contrast, other options like the Heart and Brain focus on Western disease concepts, which may not encompass the holistic and systemic approach of TCM. Similarly, the Musculoskeletal and Respiratory Systems or the Circulatory and Endocrine Systems do not represent the foundational principles of TCM diagnostics, which are deeply rooted in the concepts of Zang and Fu, their interrelationships, and how they relate to Qi, Blood, and other vital substances within
