<P> Framed in the cardiac cycle , often historically accredited to the Wiggers diagram , arterial blood has just passed through the lungs and is ready to boost oxygen to sustain the peripheral organs . The essential difference between venous and arterial blood is the curve of the oxygen saturation of haemoglobin . The difference in the oxygen content of the blood between the arterial blood and the venous blood is known as the arteriovenous oxygen difference . </P>
