Analysis of the oxygen content of blood in the frog heart and its major vessels has shown that in Rana pipiens the carotids receive primarily left atrial blood, which is highly oxygenated, whereas the pulmocutaneous vessels receive blood almost exclusively from the right atrium. Only the aortas receive blood subjected to considerable mixing.
