interventrikulärsseptum

The interventricular septum is a muscular wall that separates the left and right ventricles of the heart. This vital structure plays a crucial role in the efficient pumping of blood throughout the body. It is composed of two main parts: a muscular inferior portion and a smaller membranous superior portion. The interventricular septum prevents the mixing of oxygenated blood from the left ventricle with deoxygenated blood from the right ventricle. During fetal development, a small opening, the foramen ovale, allows some blood to bypass the lungs, but the interventricular septum is largely formed.

The integrity of the interventricular septum is essential for normal cardiac function. Disruptions to this septum, such as ventricular septal defects (VSDs), can lead to significant health problems. VSDs are congenital heart abnormalities where a hole exists in the septum, allowing blood to flow between the ventricles. The size and location of the defect determine the severity of the condition. Medical evaluation and, in some cases, surgical intervention are necessary to address these septal abnormalities. The septum's muscular nature contributes to its strength and ability to withstand the high pressures generated by ventricular contraction.
