Given below are certain groups of terms. In each group the first pair indicates a relationship between the two terms. Rewrite and complete the second pair on a similar basis. Example: Cytoplasm : Cytokinesis :: Nucleus : Karyokinesis.
Kidney : Renal artery :: Liver : __________
Topic: Hepatic artery
Answer
HEPATIC ARTERY.
The relationship is ORGAN : ARTERY SUPPLYING IT WITH OXYGENATED BLOOD. The renal artery serves the kidney, so the hepatic artery serves the liver.
HEPATIC means "of the liver", and RENAL means "of the kidney" — learning those two adjectives unlocks several terms.
BE PRECISE HERE, because the liver has THREE vessels and the analogy asks for the ARTERY: HEPATIC ARTERY — brings OXYGENATED blood from the aorta HEPATIC PORTAL VEIN — brings DEOXYGENATED blood carrying absorbed FOOD from the intestines HEPATIC VEIN — carries blood AWAY to the inferior vena cava Answering "hepatic portal vein" would be a natural slip and would break the analogy, since the renal artery carries oxygenated blood.
