Arrange these statements into the most appropriate order, reflecting what happens following initiation of the Valsalva maneuver: 1. Decrease in venous return lowers left ventricular stroke volume and arterial blood pressure. 2. Initial increase in left ventricular stroke volume raises systemic blood pressure. 3. Initial increase in left ventricular volume results in increase in left ventricular stroke volume. 4. Intrathoracic pressure is raised by expiring against a closed glottis. 5. Raised intrathoracic pressure decreases venous return to the right atrium from the systemic circulation.6.
