The mucociliary escalator is one of the major defense mechanisms, which protect the lung, and if the mucociliary escalator fails, it increases the risk that the normal and potentially pathogenic, inhabitants of the nose, throat and the back of the mouth, will descend into the lung, resulting in a potentially life-threatening pneumonia ( Anatomy and Physiology, 2013, p. 139).
Accumulators And Flow Controls Accumulators Hydraulic accumulators are used to storepressurized hydraulic fluid. The accumulatorperforms the same function in a hydrauliccircuit that a capacitor does in an electricalcircuit. Dry nitrogen is used to âpre-chargeâone side of the accumulator.A piston or sometype of rubber element (bladder or diaphragm)is used to separate the hydraulic fluid and thenitrogen.Accumulators primarily will perform two functions in the hydraulic circuit:1) Supplyadditionaloilflowtothesystemataveryfastrate.ccumulators And Flow Controls Accumulators Hydraulic accumulators are used to storepressurized hydraulic fluid.
