Atrioventricular Septum

The Atrioventricular Septum (pronounced: A-tree-o-ven-TRIK-yoo-lar SEP-tum) is a crucial part of the heart anatomy that separates the atria and the ventricles, the two main types of chambers in the heart.

Etymology

The term 'Atrioventricular Septum' is derived from Latin roots. 'Atrio' is derived from 'atrium', which in Latin means 'central room'. 'Ventricular' is derived from 'ventriculus', the diminutive form of 'venter' meaning 'belly'. 'Septum' is Latin for 'partition' or 'enclosure'.

Function

The Atrioventricular Septum prevents the mixing of oxygen-rich blood in the atria with the oxygen-poor blood in the ventricles. This separation allows the heart to pump blood more efficiently throughout the body.

Related Terms

  • Atria: The two upper chambers of the heart.
  • Ventricles: The two lower chambers of the heart.
  • Septum: A wall or partition that separates two chambers.
  • Heart: The organ that pumps blood throughout the body.

Pathology

A defect in the Atrioventricular Septum can lead to conditions such as Atrioventricular Septal Defect (AVSD), a congenital heart defect that involves a hole in the wall between the heart's upper and lower chambers and problems with the valves that regulate blood flow in the heart.
