Answer the question using the letters from the figure.

Line diagram of the liver (large outlined organ, top), gallbladder (small bean-shaped organ tucked beneath it), and kidney (bean-shaped organ, lower half) with connecting vessels. Labeled boxes with pointer lines mark individual vessels: C points to a vessel near the top of the liver; A points to a vessel running down the right side; B points to a vessel near the bottom of the paired vessels; D points to a duct near the gallbladder; E points to the single duct leaving the bottom of the kidney. Two additional boxes below read “P = Legend 4” and “Q = Legend 5”. Fig.1. Legend 1 = Liver. Legend 2 = Gallbladder. Legend 3 = Kidney. Legend 4 = All of the above. Legend 5 = None of the above.

Match the following statements with the letters in the figure above (A-E and P-Q). You may need to use the same letter more than once.

Q14.1. The figure shows vessels A-E around the liver, gallbladder, and kidney (P = "all of the above", Q = "none of the above"). Which matches: blood enters this vessel from the right ventricle?
Q14.2. Which matches: the blood carried in the vessel will drain into the left atrium of the heart?
Q14.3. Which matches: carries urine?
