Answer to Question 1

A
Pressure in fetal circulation is greatest in the right atrium, which allows a right-to-left shunt-ing that aids in bypassing the lungs during intrauterine life.
The pressure increases in the left atrium after birth and will close the foramen ovale.
The liver does not filter the blood during fetal life until the end. It is functioning by birth.
Blood bypasses the pulmonary vein during fetal life.

Answer to Question 2

C
Fetal villus tissue can be obtained as early as 10 weeks of gestation and can be analyzed directly for chromosomal or genetic abnormalities.
