Biochemical studies on mammalian cardiac muscles: I. distribution pattern of myoglobin in different chambers of the heart of some mammals.

Abstract

The myoglobin content of atria and ventricles of hearts of some mammals has been studied. The hearts of various mammals exhibit variations in their myoglobin concentration in contrast to earlier reports on various mammals. A definite gradation in the distribution pattern of myoglobin in mammalian cardiac muscles with Left atrium less than Right atrium less than Right ventricle less than Left ventricle, is discernible. There seems to be a close correlation of ventricular myocardium and their functional requirements.
