  • Prolonged bed rest or immobilization (correct)
  • Regular exercise
  • Consuming a balanced diet
  • Getting enough sleep
  • What is the mechanism behind arterial thrombosis?

  • Turbulence in the vein causing a build-up of clotting factors
  • A decrease in platelet adherence to the arterial wall
  • A build-up of lipid-filled cells in the arterial wall (correct)
  • Damage to the endothelial cells in the vein
  • What is the fate of a thrombus that undergoes dissolution?

  • It grows bigger
  • It becomes an embolus and travels to other sites in the vasculature

  • It is lysed over time and eventually reopens (correct)
  • Study Notes

    Thrombosis Risk Factors

    • Immobility is a major risk factor for thrombosis, as it can lead to stasis of blood and increase the likelihood of thrombus formation.

    Mechanism of Arterial Thrombosis

    • Arterial thrombosis is caused by the formation of a platelet-rich thrombus at the site of atherosclerotic plaque rupture, which leads to the activation of platelets and the coagulation cascade, ultimately resulting in thrombus formation.

    Fate of a Dissolved Thrombus

    • When a thrombus undergoes dissolution, it is broken down by the fibrinolytic system, which involves the conversion of plasminogen to plasmin, an enzyme that breaks down fibrin, leading to the dissolution of the thrombus.
