What type of chest tube system does this statement describe?
a. this chest drainage system has no water column to control suction but uses a suction monitor bellow that balances the wall suction and you can adjust water suction pressure using the rotary suction dial on the side of the system.
b. it allows for higher suction pressure levels, has no bubbling sounds, and water does not evaporate from it as with other systems.

Dry suction chest tube system

Explanation:

The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain.

So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.

It's also a quiet mode of activity.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
