What is ''rakta''’s relationship with blood?  ''Rakta'' is a ''dhatu'', or a flowing tissue that is responsible for the sustenance of life. Unlike what has been written in various commentaries or texts on ''rakta'', blood is not the same as ''raktadhatu''. Blood contains formed elements (RBC, WBC, platelets) which are products of ''sarakta meda'', the integral component of ''majjadhatu''. It has ''plasma'' containing minerals, vitamins, procoagulant and anticoagulant factors, enzymes, hormones, neurotransmitters, nutrients, etc., which are mostly assigned to ''rasadhatu''. Blood also contains fats, cholesterol, free fatty acids etc., which are products of ''medadhatu''. It contains blood proteins such as actin, myosin, myoglobin, etc. which are integral components of ''mamsadhatu''. It also contains metabolic wastes such as urea and lactic acid etc., which are ''mala''. Therefore, ''raktadhatu'' is a component of blood, using it as part of its material structure for its functions.
