Morphometric studies on hearts and coronary arteries of the fetal and adult oxen

Quantitative investigations were performed on hearts and coronary arteries of 10 fetal and 7 adult oxen. Relative heart weights were 0.42% in adults and 0.80% in fetuses. An interesting observation was that left coronary artery predominated by a ratio of 2.55 in adults and 1.41 in fetuses although t...

Summary:Quantitative investigations were performed on hearts and coronary arteries of 10 fetal and 7 adult oxen. Relative heart weights were 0.42% in adults and 0.80% in fetuses. An interesting observation was that left coronary artery predominated by a ratio of 2.55 in adults and 1.41 in fetuses although the percentage of left ventricular weight was similar in both adults and fetuses. Linear regressions were also determined between ventricular weights and coronary arterial diameters.
