Editing Suction (section)

== Examples ==
Pressure reduction may be [[Static pressure|static]], as in a [[piston]] and cylinder arrangement, or [[Dynamic pressure|dynamic]], as in the case of a [[vacuum cleaner]] when air flow results in a reduced pressure region.

When animals breathe, the [[Thoracic diaphragm|diaphragm]] and muscles around the rib cage cause a change of volume in the lungs. The increased volume of the [[chest cavity]] decreases the pressure inside, creating an imbalance with the ambient air pressure, resulting in suction. Similarly, when a straw is used to suck a liquid from a glass into the mouth, the atmospheric pressure on the fluid in the glass pushes the liquid up through the straw along the pressure gradient.

A common semantic mistake in aviation accident reporting is describing people or objects as being 'sucked out' during [[Uncontrolled decompression|rapid decompression]] events, when physically they are 'blown out' by the higher internal cabin pressure rushing toward the lower ambient pressure outside the plane — the opposite phenomenon to what happens when an object is placed too close to a running jet engine creating the risk of being sucked in.<ref>{{Cite web |last=Quora |title=There's No Suction In Space, Because Suction Is An Illusion |url=https://www.forbes.com/sites/quora/2016/11/21/theres-no-suction-in-space-because-suction-is-an-illusion/ |access-date=2024-01-14 |website=Forbes |language=en}}</ref><ref>{{Cite web |title=Why doesn't Earth's atmosphere escape into space? |url=https://www.spacecentre.nz/resources/faq/solar-system/earth/atmosphere-escape.html |access-date=2024-01-14 |website=www.spacecentre.nz}}</ref><ref>{{Cite web |title=NTSB Schedules Investigative Hearing on Boeing 737-9 MAX Door Plug Blowout |url=https://www.ntsb.gov/news/press-releases/Pages/NR20240312.aspx |access-date=2025-03-19 |website=www.ntsb.gov}}</ref>
