Background: Kala Sharir represents a distinctive anatomical doctrine in Ayurveda describing structural membranes situated between Dhatu (tissue) and Ashaya (visceral cavity). These membranes are not merely structural partitions but dynamic functional interfaces involved in nourishment, containment, lubrication, absorption, transformation, and reproduction. Objective: To critically analyze classical descriptions of Kala, examine commentarial interpretations, and establish systematic correlations with modern anatomical and histological structures. Methods: A qualitative conceptual review was conducted using primary classical Ayurvedic treatises including Sushruta Samhita, Charaka Samhita, and Ashtanga Hridaya, along with classical commentaries and modern anatomical literature. Structural-functional comparison methodology was applied. Results: Seven Kalas described by Acharya Sushruta show strong correlations with fascia, vascular endothelium, serous membranes, mucosal epithelium, adipose compartments, intestinal lining, and reproductive epithelium. Functional parallels include selective permeability, structural support, metabolic regulation, lubrication, and storage. Conclusion: Kala Sharir demonstrates advanced anatomical reasoning consistent with modern histological understanding. Integrative research may further validate classical Ayurvedic structural doctrines.
