Final answer:

In the systemic capillaries, the PO2 of the erythrocytes is greater than the PO2 of the plasma, causing a shift from oxyhemoglobin to deoxyhemoglobin.

Step-by-step explanation:

In the systemic capillaries, the partial pressure of oxygen (PO2) in the erythrocytes is higher than the PO2 in the plasma. This creates a pressure gradient that causes oxygen to diffuse out of the erythrocytes and into the surrounding tissues. As a result, oxyhemoglobin (Hb-O2) shifts to deoxyhemoglobin (HHb). Therefore, the statement is true.
