Ayurveda has very intensely described the Anatomy and Physiology of the human body. Acharya Charaka which supposed to be more physiological in nature which has extensive important from Chikitsa and other management of diseases. Dosha (vitiating factors or physical humors), dhatu (tissue elements) and mala (waste products) are the basic building fundamentals of the body. Their unceasing and proper flow in the body is essential to maintain health, requires hollow spaces or channels. These channels are called as ‘Srotas’ in Ayurveda. The body contains numerous channels through which the dhatus, doshas and malas circulate that are known as strotas, these consist of both gross channels, such as the arteries, veins, intestinal tract, lymphatic system and the genitor-urinary tracts etc. According Ayurvedic classic ‘Srotamayam hi shariram’ means living body is channel or comprised of channels or system. Srotas are so called because they have ‘sravana’ (oozing) – allow materials to pass through them very slowly. Srotas, in broad term refers to the channels of circulation present in the human body. These Channel which carries nutrients and give the supply to Dhatus of the body and also carry Vata, Pitta, Kapha in different Dhatus.

Human body appears to be accumulation of Srotas (channels) and proper functioning of these channels is the cause of good health. Sickness of these channels leads to the vitiation of tissue elements exist in there or passing through them, as vitiation of one leads to the vitiation of another. The vitiated channels and tissue elements vitiate other channels and tissue elements respectively. Rakta moving in its own sira performs functions such as supplying nutrition to the tissues, bestowing of colour, tactile sensation and many others also; when aggravated, rakta accumulates in their own sira, then many diseases caused by blood develop in the body. AstangaHrudayakara also have mentioned about vedhyasiras in relation to but he was not specified the sira which is to be punctured to a particular disease but he specified that siravedhana has to be done based on rogaadhisthan. He also mentions the number of avedhyasiras but his concept is that, along with 98 avedhyasiras which are mention by Sushruta, those siras which are oblique, short, tortuous, narrowly placed and which are in joints should also include in the avedhyasiras.It was observed after reviewed anatomy, physiology, circulation, venous systems, homeostasis on the grounds of literary principles, the sites of Siravyadha dealt by Sushruta are found to be correct, as bloodletting from particular site is effective in resolving the pathology of diseased conditions and beneficial in neutralizing physiological mechanisms by various changes in the body. It is very important to know the anatomy and sankhyasharir of vedhyasharir for appropriate rasktamoskhan by Siravyadh procedure [8-10].

According Ayurvedic classic ‘Srotamayam hi shariram’ means is channel or comprised of channels or system. Sushruta says that the channels of circulation are present in intra-cellular, inter-cellular and extra-cellular spaces of the human-body. Raktavahastrotas originate from the Yakrita (liver) and Pliha (spleen). Raktavahasrotas can also be comparedd with the circulatory system of the body and its Moolas will be easy to diagnosis the disease and knowing its proper anatomy in Siravedha, raktamoskahn can be done properly. Thus, it is concluded that Raktavahasrotas is nothing but entire circulatory system and the disease of the Raktavahasrotas can be treated with Siravyadha therapy.
