VENOUS RETURN MECHANISMS

• What is the primary mechanism of venous return mentioned?

  Muscle pump mechanism
• How do muscles contribute to venous return?

  Muscles contract to increase blood pressure
• What happens during active recovery in relation to venous return?

  High pressure helps blood return to the heart
• What role do valves play in venous return?

  Valves prevent backflow of blood
• What occurs when blood is pushed through a valve?

  The valve opens to allow blood flow
• What happens to the valve during systole?

  The valve closes to prevent backflow
• Why is the muscle pump important during diastole?

  It helps maintain venous return pressure
• What are the key components of venous return mechanisms?

  • Muscle pump mechanism
  • Respiratory pump mechanism
  • Valves preventing backflow
