''Pranvahasrotas'' involves the respiratory center in the brain (''prano atra murdhaga'') along with respiratory tract from nasal cavity till the alveoli. Role of ''hridaya'' is also significant. The cardio-pulmonary relationship can be easily understood in diseases like left ventricular failure with marked decrease in ejection fraction and pulmonary congestion leading to respiratory distress. ''Hridaya'' is ''mulasthana'' for ''rasavahasrotas''. ''Rasa'' and ''rakta dhatu'' are part and parcel of ''udakvahasrotas''. The content of ''udakvahasrotas'' is decided by the gastrointestinal tract. Thus one can understand why ''mahasrotas'' has been mentioned as ''mulasthana'' of ''pranvahasrotas''. | ''Pranvahasrotas'' involves the respiratory center in the brain (''prano atra murdhaga'') along with respiratory tract from nasal cavity till the alveoli.
