Both statement I and statement II are correct.
Both statement I and statement II are incorrect.
Statement I is correct but statement II is incorrect.
Statement I is incorrect but statement II is correct.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
The left ventricle pumps blood to the whole body and so has a thicker wall.
Step 2: Statement I
True: left ventricle wall is about three times thicker than the right ventricle.
Step 3: Statement II
False: columnae carneae are muscular ridges present only in the ventricles. Atria have pectinate muscles.
Final Answer:
Statement I is correct but statement II is incorrect. \[ \boxed{\text{(C) }\text{Statement I is correct but statement II is incorrect.}} \]
