What are the Tridoshas?
According to Ayurveda, the basic constituents of human body are
  • Vata

These are called Tridosha or three Humors.Tridoshas influence in all movements, all transformations, all sensory functions, and many of the other activities in the human body and mind.
Definitions in Ayurvedic treatises-
"Shareera dushanat dosha - dhatavo deha dharanat
Vata pitta kapam scheya - malini karanat mala: "    Sa/ Pu/ 5

"Vayu: pittam kaphashcheti - trayo dosha samasata:
Vikurta'vikurta deham - ghnanti te vartayanticha"   A.h/ Su /1

Tridoshas are the three fundamental principles that sustain and regulate all physiologic functions of the body. Imbalance of Tridoshas causes impairment of normal physiological function- "disease".

Elemental Composition of the three doshas:

The physical characteristics of Vata are; light, dry, mobile, cold, abundant, rough, swift etc.
Vata dosha is the most important of the three doshas. It is the main driver or mover of the body, including the other two doshas, all the tissues (dhatus) and all of the waste products (malas). When Vata becomes imbalanced for long enough and sufficiently enough, it can also cause the other two doshas (Pitta or Kapha) to become imbalanced.

Vata governs breathing, blinking of the eyelids, movements in the muscles and tissues, pulsations in the heart, all expansion and contraction, the movements of cytoplasm and the cell membranes, and the movement of the single impulses in nerve cells.
