The Mitral Valve is located between the Left Atrium ( Left upper chamber) and the Left Ventricle (Left lower chamber)
The left upper chamber of the heart is called the Left Atria and the left lower chamber is the Left Ventricle
The valve between the left atrium and ventricle is the bicuspid, or mitral, valve.
The bicuspid valve is located between the left atrium and the left ventricle. It is also called the mitral valve or left atrioventricular valve.
The wall between the two upper heart chambers is called the septum
The two large chambers at the bottom of the heart are the left and right ventricles.
A Pharoh was buried in a sarcophagus which was located in special chambers in called tombs inside pyramids in Egypt. Was this what you were looking for?
Chambers or judge's Chambers
The upper chambers of the heart are called auricles/atria and the lower chambers of the heart are called ventricles. The valve between the left atrium and the left ventricle is called the Bicuspid valve/Mitral valve. The valve between the right atrium and the right ventricle is called the Tricuspid valve.
Lobsters have gills located inside two branchial chambers. Water is pumped through these chambers by an apendage called the scaphognathite. Oxygen is extracted and the water expelled.
The chambers at the bottom are called ventricles.
The top of the heart is called the apex. The left and right ventricles are located in the apex of the heart.
Heart
The two top chambers of the heart are called the right and left auricle respectively
The bicuspid, or mitral valve (also called the left atrioventricular valve), is located between the left atrium and left ventricle. It prevents any backward flow of blood during contractions of the left ventricle.
