Heart groove Interventricular Posterior

The interventricular posterior cardiac groove (interventricular dorsal groove, dorsal longitudinal cardiac groove) is an anatomical structure located on the posterior wall of the left ventricle of the heart. It connects the apex of the heart to the base of the left atrium and is a continuation of the interatrial groove.

The posterior interventricular groove of the heart has the shape of a crescent and is located on the posterior surface of the interventricular septum. Its width is about 1.5 cm and its length is 4-6 cm.

The posterior interventricular groove contains vessels that provide blood supply to the heart and other organs. In addition, it also contains nerve fibers that are responsible for regulating heart rate and blood pressure.

The study of the posterior interventricular grooves is important for understanding the anatomy of the heart and its functions. They can be used in the diagnosis of certain heart diseases, such as myocardial infarction and arrhythmia.

Thus, the posterior interventricular groove of the heart plays an important role in the normal functioning of the heart and can be useful in the diagnosis and treatment of various diseases of the cardiovascular system.

The interventricular (posterior) groove of the heart is a deep longitudinal canal located on the posterior surface of the heart in the area of ​​​​the junction of the left and right ventricles. It is one of the main components of the circulatory system and plays an important role in the functioning of the heart.

The shape of the groove depends on how the left atrium develops, which connects to the right side of the atrium through the connecting groove. The left half of the groove gradually transforms into the interventricular groove. In addition, part of the right atrium and vestibule faces the posterior surface of the heart. Therefore, this surface of the heart has two distinct protrusions.
