The heart has two sides: the left side and the right side. Each side of the heart is divided into two parts producing 4 chambers. The upper chambers are called the atriums and the lower chambers are the ventricle. The heart not only has four chambers but also has four valves. The atri...
The avian heart is situated cranially within the coelomic cavity on the ventral midline. The right and left lobes of the liver enclose theapex of the hearton each side (Fig. 1)[3]. As in mammals, the heart has four chambers[3]. The muscle wall of the left ventricle is two to three...

The interactions investigated were those between (1) the atrium and the ve...

Two valves control blood flow within the heart’s chambers, and two valves control blood flow out of the heart. 1. The Heart Wall Is Composed of Three Layers The muscular wall of the heart has three layers. The outermost layer is the epicardium (or visceral pericardium). The epicardium ...
Starting with crocodilians, the heart pumps the blood through the pulmonary circulation and the systemic circulation by the coordinated rhythmic contractions of its upper left and right atria (LA, RA) and lower left and right ventricles (LV, RV). Each of the four heart chambers has a well-def...
