Esophageal, duodenal, urethral, and anal would all seem to fit that description.
When another tap is opened, it creates an additional demand for water in the plumbing system, causing a drop in pressure. This drop in pressure results in a decreased flow of water from the original tap as the system redistributes the water to meet the demands of both taps.
When we yawn, it can temporarily change the pressure in our ears. This can amplify sounds that we hear because the Eustachian tube, which connects the middle ear to the back of the nose and upper throat, briefly opens up.
The force that changes when the parachute opens is air resistance, also known as drag force. As the parachute opens, it increases the surface area exposed to the air, which increases the drag force acting on the parachute and slows down the descent of the object attached to the parachute.
Sodas are carbonated water. This means that carbon dioxide, CO2, has been dissolved in the water. Solubility of a gas in water is increased by pressure and by lowering temperature. So if a can of soda is warmed up, CO2 will come out from solution increasing the container's pressure. If heated enough it could burst, or if someone opens it, it would be messy.
Air resistance will increase when the parachute opens, and the decent of the skydiver will slow down.
The sphincter that opens when food or fluids exert pressure on it is the gastroesophageal sphincter. Closure of the sphincter is under the control of the vagus nerve.
The sphincter that opens when food or fluids exert pressure on it is called the lower esophageal sphincter (LES).
Lower esophageal sphincter is the sphincter that opens when food or fluid exert pressure on it. It is located at the junction of the esophagus and stomach, allowing food to enter the stomach after swallowing.
A relief valve is a safety device designed to prevent excessive pressure buildup in a system, such as a boiler, pressure vessel, or piping. It automatically opens to release pressure when it exceeds a predetermined limit, thereby protecting equipment from damage or failure. This ensures safe operation by allowing fluids to escape and maintaining pressure within safe limits. Once the pressure drops to a safe level, the valve closes again.
The Eustachian tube is the structure that opens to equalize pressure in the ear. It connects the middle ear to the back of the nose and throat, allowing air to flow in and out to maintain equal pressure on both sides of the eardrum.
A pressure switch opens or closes in response to a predefined pressure setpoint, which is determined by the internal mechanism of the switch. When the pressure in the system rises and exceeds this setpoint, the switch activates, either opening or closing an electrical circuit. The specific action—whether it opens or closes—depends on the design of the switch, which can be configured as normally open (NO) or normally closed (NC). Additionally, the pressure hysteresis settings can influence the exact point at which the switch resets after activation.

A pressure valve is usually installed on water systems to prevent excess water pressure from destroying fixtures or other plumbing components. When the pressure exceeds the valve ratings the valve opens and releases water/pressure from the line.
The ileocecal valve opens in response to pressure from the contents of the ileum pushing against it, signaling the need for passage of undigested food material into the large intestine.
Atmospheric pressure
The second tap lowers the pressure.
A pinch clothes pin primarily functions as a lever, which is a type of simple machine. It consists of a rigid body that pivots around a fulcrum, allowing the user to exert force to grip and hold items, such as fabric. By applying pressure on one end, the other end opens to release or secure the material, demonstrating the mechanical advantage of levers in everyday tasks.
