förmaksväggens

Förmaksväggen, often translated as atrial septum, is a significant anatomical structure in the mammalian heart. It is the wall that separates the right atrium from the left atrium. This partition is crucial for the proper circulation of oxygenated and deoxygenated blood. In fetal development, the foramen ovale, a flap-like opening within the foramen ovale, allows blood to bypass the lungs, which are not yet functional. After birth, this foramen typically closes, and the förmaksväggen becomes a continuous wall. However, in some individuals, a small opening may persist, leading to a condition known as an atrial septal defect (ASD). ASDs can range in severity and may require medical intervention. The integrity of the förmaksväggen is therefore vital for maintaining the separation of the two blood circulations, ensuring efficient oxygen delivery to the body's tissues. Disruptions to this wall can have significant physiological consequences.
