A blood clot is composed of which of the following components?
A. Platelets and fibrin
B. Erythropoietin and thrombin
C. Serum and albumin
D. Fibrinogen and globulin
The answer is A
Platelets and fibrin
To determine the correct answer, we can break down the question and look at each option:
A. Platelets and fibrin: Platelets are small, disc-shaped cell fragments in the blood that are involved in clot formation. Fibrin is a protein that forms a mesh-like structure during blood clotting. This option seems plausible.
B. Erythropoietin and thrombin: Erythropoietin is a hormone that stimulates the production of red blood cells, and thrombin is an enzyme involved in blood clotting. However, these components are not the primary constituents of a blood clot, so this option is unlikely.
C. Serum and albumin: Serum is the liquid portion of blood, and albumin is a protein in the blood responsible for maintaining the osmotic pressure. While both are present in the blood, they are not key components of a blood clot, so this option is unlikely.
D. Fibrinogen and globulin: Fibrinogen is a soluble protein in the blood that is converted to insoluble fibrin during the clotting process. Globulins are a group of proteins that are involved in various functions in the blood. Fibrinogen is the precursor for fibrin, which is an integral part of blood clot formation. This option aligns with our understanding.
Based on this analysis, the correct answer is A. A blood clot is composed of platelets and fibrin.
