A patient has enough plaque buildup in the left pulmonary artery to restrict much of the blood flow through this artery. What would be the most likely effect of this blockage? The left atrium and ventricle would receive less blood flow being pumped to the rest of the body. The left lung could be damaged by reduced blood flow, so oxygen needs would rely on the right lung. The right atrium and ventricle could be damaged because of a reduced flow of blood supply. The right lung would receive less blood flow being sent back to the heart and the body.
