At what temperature range must the organs be flushed with preservation solution?

The correct choice is that organs must be flushed with preservation solution at a temperature range of 4-7 degrees Celsius. This temperature range is optimal for organ preservation because it helps maintain cellular integrity and function while reducing metabolic activity.

Flushing organs at this temperature allows for effective cooling, which slows enzymatic reactions and decreases the risk of cellular breakdown during the preservation period. In addition, using a temperature that is too low can lead to ice crystal formation, which can damage the tissues and compromise the viability of the organs for transplantation.

The selected range also strikes a balance, ensuring that the organs are not too warm to initiate degradation processes, yet not so cold as to induce harmful ice formation. Hence, employing this specific temperature range is critical in the organ preservation process prior to transplantation, maximizing the chances of success.
