left atrium
A
- receives oxygenated blood
12
Q
left pulmonary veins
A
two vessels that drain oxygen-rich blood from the left lung into the heart’s left atrium
13
Q
left AV valve
A
is a heart valve that regulates blood flow between the left atrium and the left ventricle
14
Q
aortic valve
A
a heart valve that controls the flow of blood from the left ventricle of the heart into the aorta, the body’s main artery
