Given below are two statements: Statement I: The coagulum is formed of 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:
Statement I is incorrect but Statement II is correct.
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 because the coagulum (clot) is formed mainly of a network of threads called fibrins, not thrombins. Thrombin is the enzyme that converts inactive fibrinogens in the plasma into fibrins . Statement II is correct because red blood cells (erythrocytes) have an average life span of 120 days, after which they are destroyed in the spleen, making it the 'graveyard of RBCs' .
