'

Cardiac septum is a wall that separates the heart into two parts. It is composed of two types of septum, namely, the atrial septum and the ventricular septum. It helps to ensure that the right side of the heart pumps oxygen-rich blood to the lungs and the left side of the heart pumps oxygen-poor blood to the body.

The atrial septum is between the two atria, or upper chambers of the heart. It helps to prevent the mixture of oxygen-rich and oxygen-poor blood. It is important for the heart to function normally, as it prevents blood from flowing in the wrong direction.

The ventricular septum is the wall separating the two ventricles, or lower chambers of the heart. It helps to ensure that the two ventricles contract in unison and pump blood in the same direction. It also helps to ensure that oxygen-poor blood from the right ventricle is not mixed with oxygen-rich blood from the left ventricle.

If the cardiac septum does not form correctly in the womb, it can lead to various types of congenital heart defects. These include atrial septal defect, ventricular septal defect, and common atrioventricular septal defect. These conditions can cause serious health problems and require treatment.

In conclusion, the cardiac septum is an important wall that separates the heart into two parts. It helps to ensure that the right side of the heart pumps oxygen-rich blood to the lungs and the left side of the heart pumps oxygen-poor blood to the body. If the septum does not form correctly, it can lead to various types of congenital heart defects.
