Some scientists believe that the results are convincing enough to classify the suidae (swine) into a family mainly inhabited by primates, though the evidence from the entire genome disputes this. The increased systemic resistance also raises the pressure in the left atriumto be higher than the right atrium, and this causes the foramen ovale to close.[2]. b. -, Tai CL, Hsieh PH, Chen WP, Chen LH, Chen WJ, Lai PL.
