In Ayurveda, Kriyā Śarīra (क्रिया शरीर) means the functional or physiological aspect of the body.

Meaning of Kriyā Śarīra
Kriyā = function / activity / action

Śarīra = body

Kriyā Śarīra = Study of how the body functions.

Kriyā Śarīra is the branch of Ayurveda that deals with the *physiological functioning of the human body in its normal and balanced state**. It systematically explains the **dynamic activities and regulatory mechanisms* governing bodily processes based on fundamental Ayurvedic principles.

The subject primarily focuses on the *functional aspects of Doṣa, Dhātu, Mala, Agni, Srotas, and Ojas**, and their coordinated role in maintaining **homeostasis (Swasthya)**. Kriyā Śarīra elucidates the processes of **digestion, metabolism, tissue nourishment, excretion, circulation, growth, immunity, and adaptation* through the Ayurvedic framework.

By providing an understanding of *normal physiological functioning**, Kriyā Śarīra forms the **foundation for the study of Vikṛti (pathology)* and serves as a crucial basis for *clinical diagnosis, therapeutic decision-making, and preventive healthcare* in Ayurveda.

In essence, *Kriyā Śarīra represents the Ayurvedic science of physiology*, integrating structural concepts with functional dynamics to explain health and biological regulation.
