Describe adaptations made for fetal circulation in mammals.
In the fetus, the _____ is the only vessel that carries fully oxygenated blood. Describe this vessel.
Ductus arteriosus - Connects aorta and pulmonary trunk so blood flows into aorta instead of pulmonary arteries (and thus, to the lungs)
Foramen ovale - small gole between atria, diverts blood form right to left atrium, left ventricle, and then aorta, keeping blood from entering pulmonary circuit.
Umbilical vein. Flows into the inferior vena cava via the ductus venosus.
Which of the original six aortic arches are represented in the adult mammal? Describe the derivative vessel(s) of each
III - Internal carotid arteries
