The paranasal sinuses are connected to the nasal cavity through small orifices called ostia. The paranasal sinuses are joined to the nasal cavity via small orifices called ostia. The cavity of the utricle communicates behind with the semicircular ducts by five orifices. Orifices and venturi are reported to be widely used for generating cavitation. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices. They may also be manufactured with vents or orifices. The flow of real gases through thin-plate orifices never becomes fully choked. Behind, the five orifices of the semicircular canals can be found. Soon, blood streams out of his bodily orifices. The copula happens through the coaptation of the male and female genital orifices. The body is washed and the orifices are blocked with cotton or gauze. When high pressures and large orifices are encountered, then high forces are required. An intimate search is a search of the bodily orifices (other than the mouth). Because the sprinkler orifices are open, the piping is at atmospheric pressure. The airbrakes became stuck open due to hailstones blocking the orifices.
