coronary arteries
septum
The muscle that separates the right and left side of the heart is called the interventricular septum and is just a continuation of the cardiac (Heart) muscle of the heart's walls.
The SEPTUM separates the right side of the heart from the left side. This is to prevent the mixing of oxygenated blood with deoxygenated blood.
aorta
The septum.
Septum
They are the two lower chambers if the heart, responsible for pumping blood out to the body.
Septum
1)Tricuspid valve separates the right atrium from the right ventricle 2) Pulmonary (semilunar) valve separates the right ventricle from the pulmonary trunk leading to the pulmonary arteries 3) Bicuspid (Mitral) valve separates the left atrium from the left ventricle 4) Aortic valve separates the left ventricle from the aorta
"The right side of the heart is completely separate from the left side by a wall of tissue called septum. Each side has two compartments, or chambers and upper chamber and lower chamber." ~Human Biology and Health; Science Explorer; Chapter 3, Sec. 1
The division between the right and left heart is called the interventricular septum, which separates the two ventricles. This septum ensures that oxygen-poor blood on the right side of the heart does not mix with oxygen-rich blood on the left side.
The sagittal plane separates the body into left and right halves.
