Current Question (ID: 14470)

Question:

Match the vessels in Column-I with appropriate organs in Column-II: Column-I (A) Hepatic portal vein (B) Pulmonary trunk (C) Coronary circulation (D) Inferior vena cava Column-II (p) Heart's blood system (q) Returns blood to the heart from lower limbs (r) Carries blood to the liver (s) Leads to lungs

Options:

1. (A)→(r), (B)→(s),(C)→(p),(D)→(q)
2. (A)→(r),(B)→(q),(C)→(s),(D)→(p)
3. (A)→(s),(B)→(p),(C)→(r),(D)→(q)
4. (A)→(s),(B)→(q),(C)→(p),(D)→(r)

Solution:

The correct matching is: (A)→(r), (B)→(s),(C)→(p),(D)→(q). Hepatic portal vein carries blood to the liver, pulmonary trunk leads to lungs, coronary circulation is part of the heart's blood system, and inferior vena cava returns blood to the heart from lower limbs.
