Ayurveda is the science of life which not only deals with the structural and functional study of human body but also deals with its assorted pathological conditions and their appropriate management. According to Ayurvedic literature entire body is made up of Srotas (micro and macro channels) which transports all types of materials in the body. For normal functioning of the body it is essential that these channels, both micro and macro remains intact. We found detail description of Srotas is present in samhita. Srotas are related with each-other, when one Srotas is vitiated other Srotas are also get affected. Srotas is the systems that carry or circulate the Doshas and tissues (Dhatu) or their elements to the various organs. During this process of circulation the Dhatu are transformed from the first to the last tissue layer (rasa through Shukra). Each Dhatu has two aspects: nutrition for its own tissue layer, and sustenance for the next developing Dhatu.
Srotas (micro channels) are not only responsible for the dispensing of the food to different tissues and cellular systems of the body but also involved in removal of the waste products. The core of Ayurvedic medicine is the Srotas, an interconnected web of bodily functions said to conduct a healing, sacred energy from head to toe. The Srotas which means channels or path are often through to be different part of the body's transportation system. The utility of the knowledge of the Srotas (channels) is not directly described in Samhita. So there is a need to elaborate the concept of the Srotas in scientific way to realize its importance in clinical practice.
