ABSTRACT

Micrometric studies on respiratory airways of postnatal lung were done in twenty goats of
either sex with five age groups. The average diameter and epithelial height in all respiratory
segments (respiratory bronchiole, alveolar duct, alveolar sac, alveolus) exhibited an abrupt increase in goats of 2 to 3 months of age over below one month of age and became static with further advancement of age. However, thickness of blood air barrier was maximum (12.44±0.58 mm) in goats below one month and recorded thinnest (7.52±0.41 mm) in goats of 10 to 12 month of age providing most efficient diffusion pathway resulting in slow respiration rate in adults as
compared to new born kids
