An operation in which a new pathway is created for the transport of substances in the body.

A bypass of the heart and lungs as, for example, in open heart surgery. In this procedure, blood returning to the heart is diverted through a heart-lung machine (a pump-oxygenator) before being returned to the arterial circulation.

See: Coronary artery bypass graft.

hydraulic engineering - the fish diversion conduits located at intervals along the primary louver structure at the Tracy Fish Collection Facility. See schematic diagram.

The provision of telephone service without using the local exchange or toll network of a regulated telephone utility.

The bypass is a part of the feed and slurry circuit. By switching the bypass, the feed line is connected to the slurry line so that the flow in the slurry circuit can be maintained when the TBM is stopped without flushing the tunnel face. Thus, the number of repeated starting procedures for the slurry pumps is considerably reduced.
