Heart internal structure. The internal structure of the heart can be better studied by dissecting it from the ventral side. Chambers of the Heart Vertebrate hearts can be classified based on the number of chambers present. Both the auricles are thin walled.
In order to develop a more precise understanding of cardiac function it is first necessary to explore the internal anatomical structures in more detail. The right auricle and the left auricle are separated from each other by a verticle septum called interauricular septum. Module 2 Exchange and transport.
The presence of the pulmonary trunk and aorta covers the interatrial septum and the atrioventricular septum is cut away to. The right atrium lies anterior to the left atrium and the right ventricle lies anterior to the left ventricle. The right atrium receives the openings of the superior vena cava inferior vena cava and coronary sinus.
Chambers of the Heart. The opening of the inferior vena cava is guarded by a Eustachian valve. The right auricle is bigger than the left auricle.
The ventricles contract and pump blood to the arteries. Differences in thickness of the heart chamber walls are due to variations in the amount of myocardium. For instance most fish have two chambers reptiles and amphibians have three chambers.
