What is the primary aim of haemostasis?

To stop haemorrhage from damaged blood vessels

What is the term for the slowing or stoppage of blood flow?

Stasis

What is the function of proteins created in the liver during secondary haemostasis?

To stabilise the platelet plug

What is the first step in the process of haemostasis?

Formation of a platelet plug

What is the term for the process of blood clotting?

Coagulation

Haemostasis is the process of accelerating blood flow through damaged blood vessels.

False

Platelet plug formation is the secondary step in haemostasis.

False

The liver is responsible for creating proteins that form the platelet plug during haemostasis.

False

The two steps of haemostasis are the formation of a clot and the repair of damaged blood vessels.

False

The primary and secondary steps of haemostasis occur simultaneously.

False

Match the following terms with their meanings:

Haemo- = Relating to blood Stasis = Slowing or stoppage Haemorrhage = Bleeding from damaged blood vessels Coagulation = Clotting of blood

Match the following components with their roles in haemostasis:

Platelet plug = Primary haemostasis Clotting/coagulation factors = Secondary haemostasis Damaged blood vessels = Trigger for haemostasis Liver = Production site of clotting/coagulation factors

Match the following steps with their descriptions:

Primary haemostasis = Formation of a platelet plug Secondary haemostasis = Stabilization of the platelet plug by clotting/coagulation factors Haemostasis = Stopping bleeding from damaged blood vessels Coagulation = Formation of a blood clot

Match the following organs with their roles in haemostasis:

Liver = Protein production for clotting/coagulation factors Blood vessels = Site of damage triggering haemostasis Platelets = Formation of a platelet plug Heart = Pumping blood to maintain blood pressure

Match the following terms with their associations in haemostasis:

Platelet = Forming a plug to stop bleeding Clotting/coagulation factors = Stabilizing the platelet plug Liver proteins = Part of the secondary haemostasis process Blood vessels = Site of haemostasis

What is the purpose of haemostasis?

To stop haemorrhage from damaged blood vessels

What is formed during primary haemostasis?

A platelet plug

What stabilizes the platelet plug during secondary haemostasis?

Proteins created in the liver

What is the source of clotting/coagulation factors during secondary haemostasis?

Liver

What is the term 'haemostasis' derived from?

Haemo- meaning blood and -stasis meaning slowing or stoppage

What is the main purpose of haemostasis?

To stop haemorrhage from damaged blood vessels

What is the source of clotting/coagulation factors during secondary haemostasis?

The liver

What is the primary step in the process of haemostasis?

The formation of a platelet plug

What is the function of proteins created in the liver during secondary haemostasis?

To stabilise the platelet plug

What is the term 'haemostasis' derived from?

Haemo- meaning 'blood' and -stasis meaning 'slowing or stoppage'

Haemostasis is the process of accelerating blood flow through damaged blood vessels.

False

The primary step in haemostasis is the formation of a clot.

False

The liver is responsible for creating proteins that stabilize the platelet plug during haemostasis.

True

Primary haemostasis and secondary haemostasis occur simultaneously.

False

The primary aim of haemostasis is to repair damaged blood vessels.

False

What happens to the platelets when a blood vessel is damaged?

They adhere to the inner surface of the vessel

What is the purpose of the platelet plug in primary haemostasis?

To initially plug the defect, but not as a long-term fix

What happens to activated thrombocytes in primary haemostasis?

They release substances to attract more thrombocytes

What is the result of the accumulation of thrombocytes in primary haemostasis?

The creation of a temporary platelet plug

How often does primary haemostasis occur in the human body?

Daily, as a natural process

The primary aim of haemostasis is to accelerate blood flow through damaged blood vessels.

False

Platelet plug formation is a long-term fix for damaged blood vessels.

False

Thrombocytes are involved in the process of primary haemostasis.

True

Primary haemostasis occurs rarely in the human body.

False

Activated thrombocytes become less sticky to other thrombocytes in primary haemostasis.

False

What is the function of fibrin in secondary haemostasis?

To stabilise the platelet plug

What is the result of secondary haemostasis?

A thrombus is formed

What gets trapped in the platelet plug during secondary haemostasis?

Red and white blood cells

What is the term for the formation of a thrombus?

Secondary haemostasis

What is the role of coagulation factors in secondary haemostasis?

To activate fibrin

What is the purpose of fibrin in secondary haemostasis?

To stabilize the platelet plug and hold it in place

What type of cells get trapped in the platelet plug during secondary haemostasis?

Red and white blood cells

What is the term for the formation of a thrombus?

Secondary haemostasis

To activate fibrin to stabilize the platelet plug

What is the result of secondary haemostasis?

Formation of a thrombus

Understand the process of haemostasis, including primary and secondary haemostasis, and how they work together to stop bleeding from damaged blood vessels. Learn about the role of platelets and clotting factors in the coagulation process.
