None of the above

Detailed explanation-1: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
Detailed explanation-2: -The left ventricle connects nearly all organ systems through its function to pump oxygenated blood to the body. Left ventricular failure would likely result in impairment to all other organ systems. Organs may react to low ventricular function by initiating mechanisms to increase blood delivery.
Detailed explanation-3: -When the left ventricle contracts, the mitral valve closes and the aortic valve opens. This is so blood flows into the aorta and out to the rest of the body.
