Question

Short note on suction mechanism.​

Answer 1

Answer:

In pulmonary hygiene, suction is used to remove fluids from the airways, to facilitate breathing and prevent growth of microorganisms. Small suction-providing devices are often called aspirators. ... Suction devices may be mechanical hand pumps or battery or electrically operated mechanisms.

Answer 2

Suction is the force that a partial

vacuum exerts upon a solid, liquid, or a gas. When the pressure in one part

of a system is reduced relative to

another, the fluid in the higher pressure region will exert a force relative to the region of lowered pressure.
