The word 'suction' refers to the process of drawing air, liquid or solid material into a space or container using a vacuum or a suction device. For example, if you use a vacuum cleaner to clean your home, it uses suction to draw up dirt and debris from the floors and carpets. Similarly, doctors may use suction devices to remove fluid or air from a patient's lungs or other bodily organs during surgery. The word 'suction' is commonly used in medical, engineering and cleaning contexts.
