To stabilise the platelet plug and hold it in place
What is the term for the formation of a thrombus?
Secondary haemostasis
What is the purpose of red and white blood cells getting trapped in the platelet plug?
To make the platelet plug stronger
What is the outcome of the activation of coagulation factors?
Activation of fibrin
What is the term for the stabilised platelet plug?
Thrombus
Fibrin is produced by platelets during secondary haemostasis.
False
The platelet plug is stabilised by the activation of red and white blood cells.
False
Secondary haemostasis is the initial response to blood vessel injury.
False
The mesh-like fibres formed during secondary haemostasis are composed of platelets.
False
The formation of a thrombus is a weak and temporary response to blood vessel injury.
False
What is the role of coagulation factors in secondary haemostasis?
To activate fibrin to stabilise the platelet plug
What is the outcome of the stabilisation of the platelet plug?
A stronger platelet plug due to the trapping of red and white blood cells
What is the composition of the mesh-like fibres formed during secondary haemostasis?
Fibrin
What is the function of fibrin in the platelet plug?
To stabilise the platelet plug
What is the result of the formation of a thrombus?
A strong response to blood vessel injury
Once the platelet plug has formed, ______ factors are activated which then causes a protein called fibrin to stabilise the platelet plug and hold it in place.
coagulation
Fibrin stabilises the platelet plug and holds it in place with ______ that work like a mesh.
fibres
Red and white blood cells may also get trapped in the plug – makes it ______.
stronger
The platelet plug then becomes a ______.
thrombus
Secondary haemostasis is the formation of a ______.
thrombus
Match the following components with their roles in secondary haemostasis:
Fibrin = Stabilises the platelet plug and holds it in place with mesh-like fibres Coagulation factors = Activates fibrin to stabilise the platelet plug Red and white blood cells = Get trapped in the platelet plug to make it stronger Platelet plug = Initially forms in response to blood vessel injury
Match the following statements with their correct descriptions:
Secondary haemostasis = Formation of a thrombus Platelet plug = Initial response to blood vessel injury Fibrin = A type of blood cell Coagulation factors = Proteins that activate fibrin
Match the following with their effects on the platelet plug:
Fibrin = Stabilises the platelet plug Coagulation factors = Activates fibrin to stabilise the platelet plug Red and white blood cells = Make the platelet plug stronger Platelet plug = Initially forms in response to blood vessel injury
Match the following components with their functions in the formation of a thrombus:
Fibrin = Forms mesh-like fibres Coagulation factors = Activate fibrin to form mesh-like fibres Platelet plug = Initially forms in response to blood vessel injury Red and white blood cells = Get trapped in the thrombus to make it stronger
Match the following with their outcomes in secondary haemostasis:
Fibrin formation = Stabilises the platelet plug Coagulation factor activation = Causes fibrin formation Red and white blood cell trapping = Makes the platelet plug stronger Platelet plug formation = Initially responds to blood vessel injury
What is the primary function of fibrin in secondary haemostasis?
To stabilise the platelet plug and hold it in place
What is the main difference between the platelet plug and a thrombus?
The platelet plug is unstable, while the thrombus is stable
Why do red and white blood cells get trapped in the platelet plug?
To make the platelet plug stronger
What is the result of the activation of coagulation factors in secondary haemostasis?
The stabilisation of the platelet plug
What is the final outcome of secondary haemostasis?
The formation of a thrombus
Learn about the secondary haemostasis process where coagulation factors are activated to form a thrombus, stabilising the platelet plug and holding it in place. Understand how fibrin creates mesh-like fibres to strengthen the clot.
