There is provided a technique of, when an organ is preserved outside a body while being perfused with a liquid, ensuring the flow rate of the liquid flowing in the organ while suppressing a rise in pressure in the liquid. An organ preservation system (1) includes an organ container (10), an organ holder (20), a liquid supply tube (40), a drainage tube (50), and an atmospheric pressure regulator (60). The organ container (10) is capable of having therein an organ preservation space (13) that is a confined space. The organ holder (20) holds the organ (9) in the organ preservation space (13). The liquid supply tube (40) supplies a liquid to the organ (9) held by the organ holder (20). The drainage tube (50) discharges a liquid from the organ (9) held by the organ holder (20). The atmospheric pressure regulator (60) regulates atmospheric pressure in the organ preservation space (13). By regulating atmospheric pressure in the organ preservation space (13), it is possible to adjust a pressure in the liquid flowing in the organ (9). Accordingly, it is possible to ensure the flow rate of the liquid flowing in the organ while suppressing a rise in pressure in the liquid.
