(Top right) External view of human heart 277 in systole and attached to the system. (Center) Flow diagram for a functional heart and lung reanimation consisting of: (1) a respirator connected to the cannulated trachea and thus attached to the lung(s), (2) a pre-load chamber for the right side of the heart, (3) an aortic after-load chamber which mimics the resistance that the left ventricle works against, (4) a left pre-load chamber employed when only one lung is present, (5) an oxygenator reservoir for pooling fluid expelled by any cannulated branch of the pulmonary artery, (6 & 7) fluid pumps to maintain the pre-load pressures, (8) hemostasis valves that allow access for delivery of cameras, instruments, and assorted devices, (9) valves that may also be used to redirect flow as physiologically appropriate, while (10) cannulation of the pulmonary vein(s) are shown here for a right lung preparation, but are absent or translated when either both lungs or the left alone respectively are used
