the left atrium
The right atrium is where the blood enters the heart.
In the pulmonary circulation, deoxygenated blood leaves the right section of the heart through the pulmonary artery, enters the lungs and oxygenated blood comes through the pulmonary veins. The blood then moves to the left atrium of the heart.
The left atrium is the chamber that receives oxygenated blood returning from the lungs.
Blood returning from the body systemic circulation first enters which chamber of the heart?
It enters the right chamber called right atrium
Yes and no. When a valve is open, it is allowingblood to enter the heart's chambers. When a valve is closed, it is preventing blood from entering a chamber.
The left ventricle pumps oxygenated blood into the aorta, one of the first side branches of the aorta are the cardiac arteries that bring blood back to the heart. So no heart chamber supplies blood to the heart directly.
