Question

Given are the sets of terms. Identify the odd term. Write the category of the other.

• A. Inguinal canal
• B. Coronary arteries
• C. Lachrymal glands
• D. Wisdom teeth
• E. Bile duct

Answer 1

Answer: (D)

Wisdom teeth

1. The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle.
2. The lacrimal glands are paired exocrine glands, one for each eye, found in most terrestrial vertebrates and some marine mammals, that secrete the aqueous layer of the tear film.
3. The inguinal canals are the two passages in the anterior abdominal wall of humans and animals which in males convey the spermatic cords and in females the round ligament of the uterus.
4. The bile ducts are a series of thin tubes that go from the liver to the small intestine. Their major job is to move a fluid called bile from the liver and gallbladder into the small intestine, where it helps digest the fats in food.
5. Wisdom teeth are the last of our teeth to appear (erupt) in the mouth. Impacted wisdom teeth are third molars at the back of the mouth that don't have enough room to emerge or develop normally. Wisdom teeth are the last adult teeth to come into the mouth (erupt).
6. Hence, the odd one out is the Wisdom teeth as all the mentioned structures are present in our body from birth except the wisdom teeth that may or may not emerge on attaining adulthood.
7. So, the correct option is 'D'.
