    What is the body’s response to a rise in blood plasma osmotic pressure?

    Cardiovascular System
    A suction pump when used to clear an obstructed airway expands the volume in its chamber to:
    A suction pump produces a “negative” pressure (one that is less than atmospheric pressure). Hence air in the lungs will flow out into the suction pump, hopefully pushing the obstructing liquid out too.
