- Blood Clots (CVD)
- Formation of a blood clot
- Thromboplastin released from damaged blood vessel
- Thromboplastin and calcium ions (from plasma) trigger conversion of Prothrombin to Thrombin
- Thrombin starts conversion between Fibrinogen and Fibrin
- Fibrinogen is a soluble protein, Fibrin are solid insoluble fibres
- Fibrin fibres tangle and form a mesh, trapping platelets and red blood cells
- Blood clot is formed
- Prothrombin is a soluble protein, Thrombin is an enzyme
- Thrombin starts conversion between Fibrinogen and Fibrin
- Thromboplastin is a protein
- Thromboplastin and calcium ions (from plasma) trigger conversion of Prothrombin to Thrombin
- Thromboplastin released from damaged blood vessel
- Can result in...
- Heart attacks
- Blood contains oxygen needed by heart muscle cells for respiration
- If the arteries are blocked by a blood clot, it cuts off the blood supply, less oxygen to reach the heart muscle.
- Causes a heart attack
- Heart attacks can cause damage and death of the heart muscle
- Symptoms:
- Pain in chest
- Shortness of breath
- Sweating
- Symptoms:
- Heart attacks can cause damage and death of the heart muscle
- Causes a heart attack
- If the arteries are blocked by a blood clot, it cuts off the blood supply, less oxygen to reach the heart muscle.
- Blood contains oxygen needed by heart muscle cells for respiration
- Strokes
- Rapid loss of brain function
- Due to disruption in blood supply to the brain
- can be caused by a blood clot, reducing how much oxygen can reach the brain
- Due to disruption in blood supply to the brain
- Rapid loss of brain function
- Deep vein thrombosis
- Formation of a blood clot in a vein deep into the body
- Most common in leg veins
- Caused by prolonged inactivity, increased risk with age
- Most common in leg veins
- Formation of a blood clot in a vein deep into the body
- Heart attacks
- Coronary Heart disease, arteries have a lot of atheromas, restricting blood flow
- Increases risk of blood clot formation
- Formation of a blood clot
