It is comprised of the blood vessels in the placenta and the umbilical cord, which contains two umbilical arteries and one umbilical vein. Blood commences flowing through the lungs, and the pressure on the left side becomes higher than on the right. The major difference appears to be how long it takes to reach each of these same stages. After birth, erythropoiesis will also slow. Many of these are truely historic, and while essentially wrong, science works through testing these alternate theories, and is some cases some can even be partially correct. What are the functional roles of the umbilical artery and vein in fetal pig anatomy and physiology? In pre-ductal coarctation of the aorta, deoxygenated blood travels from the right atrium to the right ventricle and then through the pulmonary artery. Pigs and humans are mammals and give birth to young ones; they share various similarities. The Genetics of the Dog.

Surprisingly, there is no difference other than the length and thickness of the ureters and urethra. Amphibians and mammals have a double circulation system, but their cardiac physiology is different. Current developmental biology shows that this is not the source of primordial germ cells or follicle components, but is a cuboidal epithelium overlying a dense connective tissue layer (tunica albuginea).
