Question 5 (Multiple Choice Worth 2 points)
(06.05 MC)This is a two-part diagram showing maternal circulation on the left and fetal circulation on the right. Letter A indicates a large crescent-shaped organ that contains blood from the maternal circulation and blood from the fetal circulation. A large tube containing arteries and veins extends out from the crescent-shaped organ into the fetal circulatory system. The tube is labeled letter C. Letter B indicates a junction within the fetal circulatory system at which an artery from the tube indicated by letter C connects with a large blue vein extending down from the heart. This connection occurs very close to the liver. Letter D indicates a connection between the large blood vessel that extends from the right atrium of the fetal heart and a large, arch-shaped vessel that connects to the left ventricle of the fetal heart.Image Courtesy of 3DScience.com

Question 13 (Multiple Choice Worth 2 points)
(04.02 MC)
According to the National Institute of Health, peripheral arterial disease (PAD) happens when there is a narrowing of the blood vessels outside of your heart. The cause of PAD is atherosclerosis. This can reduce or stop blood flow, usually to the legs, causing them to hurt or feel numb. If severe enough, blocked blood flow can cause tissue death. If this condition is left untreated, a foot or leg may need to be amputated.
Based on the passage above, which of the following would indicate PAD?
Low flexibility of blood vessels and increased number of white blood cellsHigh flexibility of blood vessels and decreased number of white blood cellsLow flexibility of blood vessels in the limbs and high blood pressureHigh flexibility of blood vessels in the limbs and low blood pressure
