Gas exchange initially occurs in the yolk sac until the placenta entirely takes over. Pre-ductal indicates that the constriction is before the ductus arteriosus and post-ductal indicates that the constriction is after the ductus arteriosus. On the otherhand, oxygenated blood returns to the left side of the heart from the lungs and then travels through the pulmonary artery to go back to the lungs. VBW and VBD of calf cervical vertebrae were larger than those in humans, but the spinal canal was smaller. Describe two ways that the internal anatomy of the fetal pig differs from that of a human.
