Despite dramatic movie portrayals, the human body does not explode when exposed to a vacuum. Instead, the real and immediate dangers begin with the terrifying consequences of attempting to breathe in a vacuum, where oxygen is violently stripped from the blood.

The history of surgical suction dates back to the early 20th century with the invention of the Yankauer tip around 1907, highlighting the fundamental importance of understanding **what is the purpose of suction in surgery**. This technology has evolved to become a crucial component of patient safety and surgical precision in almost every type of medical procedure.

The principle behind suction is a fundamental concept in physics, relying on the creation of a pressure differential. This is the simple and powerful scientific secret that explains **how do suction tubes work?**, drawing fluids and air in a controlled and precise manner in both medical and industrial settings.

In physics, pressure cannot truly be a negative value, as it is defined as force per unit area, which must always be positive. Therefore, **what do you mean by negative pressure** is understood as a relative term, where an area has lower pressure compared to its surroundings. This fundamental principle has vital applications in various fields, especially in healthcare and engineering.
