It is simply called a key
ANY MACHINED BAR CAN BE CALLED AS ROD, IT TRANSFERRS MOTION FROM ONE LINK TO ANOTHER..................IF THE SUPPLIED MOTION IS OF TORSIONAL TYPE(WHICH TENDS TO ROTATE THE LINK ON ITS OWN AXIS) THE SAME ROD IS CALLED A SHAFT... RANA PRAKASH ranaprakash2873@gmail.com

Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.
The principle parts of a centrifugal pump are the pump casing, also called a volute, and the impeller. The other parts are the pump shaft, bearing(s), shaft seal, the wear rings, and the inlet and outlet. The impeller is mounted on the pump shaft. The pump shaft is coupled to an external power source like a motor. The motor turns the shaft, the shaft makes the impeller turn and the fluid being pumped is put in motion. The volute causes a change in pressure in the fluid. The shaft seal stops the fluid from leaking out of the casing (volute). The wear rings separate the high and low pressure areas inside the casing. The bearing(s) make the shaft turn easier. The inlet and outlet parts of the casing connect to the fluid piping system.
A horizontal mine shaft is called an adit. en.wikipedia.org/wiki/Adit

An air shaft is a vertical shaft which supplies ventilation to a tunnel or underground facility.
Shaft mining is the earnest form of underground mining. Underground mining is selected when the rock or mineral is so far to reach using surface mining. Shaft mining is the kind of mine that you normally see in movies where the miner travels straight down into a profound, dark tunnel until he reaches the base. The shaft mine has a vertical man shaft, a tunnel where the men travel up and down in an elevator. Equipment is taken into the mine using this shaft, too. Short tunnels to the ore are dug from that man shaft. When the ore is dynamited and broken into chunks, it is taken to the top and loaded into trucks through a second shaft. There is usually an air shaft that gives the mine ventilation. When we visited a coal mine, it was amazing how much air moved around in the tunnels. Moving air removes the gases that occur naturally underground.
An adit. In North America, the horizontal or sloped entrance to a mine is called a "Portal". Portal more specifically refers to the portion of the shaft visible from the outside of the mine. In some areas, the Portal portion of a horizontal shaft is called the "Drift Mouth" or "Drift Portal" as this shaft leads into a "Drift Mine". With a vertical shaft, that portion would be called a "Collar".

Cliffs Shaft Mine Museum was created in 1880.
it is in the mine thing
A pit is open, whereas a mine has a ventilation circuit.
