Atrioventricular Foramen Right

Right atrioventricular foramen: structure and functions

The right atrioventricular foramen (RAV) is the opening that is located between the right atrium and the right ventricle of the heart. It is one of the key components of cardiac anatomy and plays an important role in maintaining blood circulation in the body.

The structure of the atrioventricular orifice of the right

PDA has several synonyms such as ostium atrioventriculare dextrum, pna, jna, ostium venosum and bna. It is ring-shaped and surrounded by the annular leaflets of the tricuspid valve. The annular leaflets of the tricuspid valve ensure reliable closure of the PDA during systole and prevent backflow of blood from the ventricle into the atrium.

Functions of the right atrioventricular orifice

The PDA plays a key role in maintaining normal blood circulation in the body. During diastole, when the right atrium myocardium is relaxed, blood from the superior and inferior vena cava enters the right atrium through the PDA. During systole, when the myocardium of the right ventricle contracts, blood is pushed out of the ventricle into the pulmonary artery for further distribution to the lungs.

In addition, the PDA is a key site for medical procedures such as cardiac catheterization and insertion of pacemakers and other medical devices.

Conclusion

The right atrioventricular orifice plays an important role in ensuring normal blood circulation in the body. Its structure and functions allow the heart to pump blood efficiently and keep the body healthy. Understanding the anatomy and function of the right atrioventricular foramen is of great importance for medical procedures and the treatment of cardiovascular diseases.

The atrioventricular opening (AVO) is one of the most complex anatomical elements of the human cardiovascular system. The importance of the PVC lies in the fact that it provides communication between the atrium and the ventricle of the heart. In this sense, it is a kind of door between the chambers of the heart. However, the PVC is an important element of the work of the heart muscle.

The atria are cavities in the heart where blood accumulates before it enters the ventricles of the heart. In order for blood to move to the ventricles, the atria must be connected to the ventricles. This process occurs through the PJO.

Fluctuations in the functioning of the pancreas can lead to the development of various heart diseases, such as heart failure, arrhythmia, coronary artery disease and others. One of the important aspects of understanding PJO is its correct identification and knowledge of its location in the body. This is necessary for successful surgical and therapeutic diagnosis and treatment of cardiovascular diseases.

The main anatomical features of the PVC include: - Location: The PVC is located at the junction of the right atrium and the right ventricle. - Shape and size: The atriogastric opening is oval in shape and varies depending on
