Functioning of human organs according to Siddha Medicine

The three humors are responsible for the functioning of the human organism according to the siddha. When the three Doshas Vata, Pitta and Kapha reside undisturbed in their proper organs and tissues, the organism is supported by them and is in balance. When disturbed, they cause disease and deterioration of the body.
Of all of them, Vata (Wind) is the key. Pitta and Kapha cannot move from their centers unless the air within the body carries them.
