Where the left atrium is, in 3D
The left atrium is the chamber that receives oxygen-rich blood from the lungs. It is part of the heart and belongs to the cardiovascular system. It sits at the back of the heart, forming most of its base, and usually receives four pulmonary veins. The mitral valve separates it from the left ventricle.
Frequently asked questions
Which body system does the left atrium belong to?
The left atrium belongs to the cardiovascular system. The cardiovascular system is made up of the heart and the blood vessels: arteries, veins and capillaries.
What else can you see alongside the left atrium?
The BAHI BODY 3D model of the heart also shows the right atrium, right ventricle, left ventricle, tricuspid valve, pulmonary valve, mitral valve, aortic valve, aorta, pulmonary trunk, superior vena cava, inferior vena cava, brachiocephalic trunk, brachiocephalic veins, common carotid arteries and subclavian arteries.
Where is the heart?
The heart is a muscular organ in the middle of the chest, slightly to the left, between the lungs.
What lies directly behind the left atrium?
The oesophagus. The left atrium is the most posterior chamber of the heart.
