The five elements described above form three biological humors (Doshas) – Vata, Pitta and Kapha. Every living being is a balance of the three doshas in different and unique proportions and manifestations. Vata dosha is responsible for movement and communication, and it represents all neurological activities in the body. Pitta dosha is responsible for the transformation, digestion and metabolism of food and nutrients, and governs all hormonal and enzymatic actions. Kapha dosha is responsible for structure, cohesion, binding and lubrication, and governs all immunological activities and structural functions.
