Answer to Question 1

ANS:
5, 8, 1, 3, 6, 4, 2, 7

Blood travels through the fetus in a unique pattern. Most blood enters the inferior vena cava through the ductus venosus, empties into the right atrium, and passes through the foramen ovale into the left atrium. It then travels to the left ventricle, into the aorta, and out into the rest of the systemic circulation. Blood returns to the heart from the head through the superior vena cava, goes through the right side of the heart before entering the pulmonary artery, or bypasses the lungs and enters the aorta through the ductus arteriosus.

Answer to Question 2

ANS: A, B, D, E
TORCH stands for toxoplasmosis, other infections, rubella, cytomegalovirus, and herpes simplex virus. Other infections include varicella zoster virus, human immunodeficiency virus, hepatitis B virus, human parvovirus B19, and syphilis. Roseola is not included.
