This study was conducted to elucidate the effects of age and sex on the histometrical values of blood pressure related organs including heart, kidneys and adrenal glands in teddy goats. The hearts, kidneys and the adrenal glands of 36 teddy goats, divided in three age-groups; kids (6-12 months), adults (13-21 months) and adults (22-24 months), were processed for histometrical studies. Mean diameters, volumes and Intramural connective tissue contents of right atrium, left atrium, right ventricle and left ventricle were recorded from cardiac specimens. Age affected none of the parameters of the heart significantly. Mean diameters and volumes of subcapsular and juxtamedullary glomeruli were recorded from kidney specimens. All parameters of the kidney invariably showed a consistent rise with advancing age. Thicknesses of the zona glomerulosa, zona fasciculata and zona reticularis of the right adrenal gland were measured. Thickness of different zones of the adrenal cortex showed significant (P<0.05) changes with age. It is conceivable from these findings that the development of heart, kidneys and adrenal showed an increase parallel to the advancing age to adjust with the increasing blood pressure due to physiological development process. Sex, however, played a secondary role.
