Given below are two statements:
Statement I: The coagulum is formed of a network of threads called thrombins.
Statement II: Spleen is the graveyard of erythrocytes.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both statement I and Statement II are correct
• B. Both statement I and Statement II are incorrect
• C. Statement I is correct but statement II is incorrect
• D. Statement I is incorrect but statement II is correct

Answer 1

Answer: (D)

Statement I is incorrect but statement II is correct

Answer 2

The correct answer is (d).
Blood clot or coagulum is formed mainly of a network of threads called fibrins in which dead and damaged formed elements of blood are trapped, so the statement, coagulum is formed of a network of threads called thrombins is incorrect. RBCs have an average life span of 120 days after which they are destroyed in the spleen, hence the spleen is called the graveyard of RBCs).
