Concept of Srotas and Micro Channels of Circulation in Body

The concept of Srotas in Ayurveda is foundation to understand human anatomy, physiology and pathology. Ayurveda describes the human body as a vast network of channels known as Srotas, which facilitate the movement of nutrients, wastes, energies, and vital essences. Srotas represent pathways for the transportation of substances essential for maintaining homeostasis and health. Classical Ayurvedic texts identify multiple Srotas responsible for specific bodily functions, emphasizing that health depends on their unobstructed flow. These channels exist at multiple structural and functional levels. To better understand their complexity, Srotas can be broadly categorized into macro channels (Sthūla Srotas) and micro channels (Suksma Srotas).
