Volumetric growth of various aortic segments in human fetuses 75Correlation coefficients (r) or coefficients of determination(R 2 ) between parameters examined were estimated.A priori level of significance was set at P0.05). Hence the morphometric values obtained,without regard to sex, have been presented in Table II.Fig. 1.
