a blood vessel in the liver has blood with pp of oxygen same as that in the tissues of the liver. but there is diifference in co2 pp.Does the oxygen diffuse into the blood from the tissues or from the blood into the tissues?

CO2 transference actually occurs in the capillaries. Blood travels from the heart to the lungs, where it picks up oxygen. Aortic blood is oxygen rich, and brings oxygen to all the other parts of the body. Ventricular blood pulls CO2 away from the organs. The meeting place is where the vessels narrow to be as small as 1 cell in width- in the capillaries, where oxygen is exchanged for CO2, and arterial blood becomes venous blood, completing the cycle back through to the heart. Capillary beds surrounding each major organ do the exchange for that region (IE lungs, where excess CO2 is removed).

That would depend on the pp of CO2. If the pp of CO2 in the liver is higher, some CO2 bind to hemoglobin and the affinity of hemoglobin for oxygen decreases (because of the conformational changes of hemeglobin). Thus, oxygen is released to the tissues of the liver.
Carbon dioxide binds to hemeglobin to form carbaminohemoglobin, producing H+ that will stabilise T state and promote release of oxygen.
If the pp of CO2 in liver is lower, the reverse occurs. For more info about T and R states, and details about the conformation of hemeglobin, i would recommend looking it up in an introductory biochemistry textbook.
