ABSTRACT

Srotas is defined as the passages through which the various dhatus that are undergoing the process of metabolic transformation are transported. The process of transformation of dhatu requires the action of Agni. Srotorodha is one of the samalakshana by Vagbhata. Srotasas are related to the metabolic state of their corresponding tissues through different tissues. Srotasas are also described to be the structures from which the contents move out, or ooze out, or transude out. Nutrient substances are supplied to various tissues via Srotas. Concept of srotas is similar to functional system indicated in physiology of living body. When organs carrying out same function are working together, they collectively comprise a system. Pranavaha system deals with inhaled flow of air. Since heart is principle organ of this system, all active entities working for heart can be considered supportive to this system. Commentator Chakrapani straight away indicates respiratory system should be considered as Pranavaha srotas. He also states that Prana indicates one of five types of Vatadosha. Diseases of this system match respiratory diseases hence it can be concluded that Pranavaha srotas indicates respiratory system.
