A Fibrin Network That Contains Trapped Blood Cells and Platelets

Question

A fibrin network that contains trapped blood cells and platelets is called a(n)
A) platelet plug.
B) rouleaux.
C) agglutinin.
D) blood clot.
E) lysin.

Accepted Answer

A blood clot forms when a fibrin network traps blood cells and platelets together, creating a solid clot that can help stop bleeding. Choice A (platelet plug) refers to the initial aggregation of platelets at the site of injury. Choice B (rouleaux) refers to the stacking of red blood cells in a coin-like formation, which can occur in certain conditions but is not related to clotting. Choice C (agglutinin) refers to an antibody that causes clumping (agglutination) of cells, but again, this is not related to clotting. Choice E (lysin) refers to a substance that breaks down cells, also not related to clotting.
