Ayurveda describes a systemic inner transport system comprising of gross and minute as well as very subtle channels transporting not only biological fluids, nutrients and waste products but also energies and impulses in different biological settings. These are generically called srotamsi or channels. The srotamsi are innumerable but 13 gross channels are clinically approachable and are affected in different disease states with specific manifestations. These 13 gross channels comprise of three channels which transfer life-support substances from outside to inside the body and are called pranavaha, udakavaha and annavaha srotas. Another three  channels perform gross excretory functions and remove feces, urine and sweat and are called purishavaha, mutravaha and swedavaha srotas respectively. The remaining seven channels are for sustenance of the seven primordial tissues or dhatus and are collectively called saptadhatus.

[https://en.wikipedia.org/wiki/Ayurveda Ayurveda] describes a systemic inner transport system comprising of gross and minute as well as very subtle channels transporting not only biological fluids, nutrients and waste products but also energies and impulses in different biological settings. These are generically called ''srotamsi'' or channels. The ''srotamsi'' are innumerable but 13 gross channels are clinically approachable and are affected in different disease states with specific manifestations. These 13 gross channels comprise of three channels which transfer life-support substances from outside to inside the body and are called ''pranavaha, udakavaha'' and ''annavaha srotas''. Another three  channels perform gross excretory functions and remove feces, urine and sweat and are called ''purishavaha, mutravaha'' and ''swedavaha srotas'' respectively. The remaining seven channels are for sustenance of the seven primordial tissues or ''dhatus'' and are collectively called ''saptadhatus''.

   

   

Besides these gross channels, the living body has innumerable micro-channels responsible for secretion, synthesis and microcirculation of different life substances. According to Charaka, there are as many srotamsi as there are life-factors operating in the body.

Besides these gross channels, the living body has innumerable micro-channels responsible for secretion, synthesis and microcirculation of different life substances. According to Charaka, there are as many ''srotamsi'' as there are life-factors operating in the body.

These channels are prone to getting vitiated and obstructed, a fundamental reason for all pathologies in the body-mind system. Ama, the byproduct of diminished agni, is the most common cause of srotodushti (vitiation of transport system). There are four broad categories of srotas morbidity viz. hyperactivity, hypoactivity, distortions and swellings, and diversions of pathway. It is imperative to conserve the integrity of the srotamsi for good health. Ayurvedic srotovijnana is a unique approach to the understanding of macro, micro and molecular dimensions of the inner transport system of the living body.
