siphon-, siphono- +

1. The removal of liquids or gas by means of a siphon utilizing gravitational pressure, particularly as a means of emptying a body cavity.
2. In medicine, the use of a siphon, as in gastric lavage or in draining the bladder.

A "gastric lavage" refers to the process of washing out a hollow organ; especially the stomach, by flushing with water.

Fleas, a large order of snail, sclerotized (hardening of a tissue), wingless insects with bloodsucking mouth-parts and strong jumping legs.

More than 800 species have been described of these ectoparasites on birds and mammals.

Possessing or characterized by siphons; tubular, in algae, a form consisting of a more-or-less elaborate multinucleate thallus (having two or more nuclei of the body of an organism; such as, an alga or liverwort that is not differentiated into leaves, stems, and roots).

1. The honey dew tube of an aphid.
2. One of the two dorsal tubular organs on the back part of the abdomen of aphids.

Fertilization by means of a pollen tube through which contents of pollen grain pass to the embryo sac.

In anthozoan sea anemones (an invertebrate ocean animal with a roundish hollow body), a ciliated groove at one or both ends of the slit-shaped mouth, thought to help circulate water in the gullet.

A copepod is a tiny crustacean that lives among plankton and is an important food source for many fish. Native to oceans and lakes.

A device that is designed to greatly speed up the fluid flowing in a pipe so an inlet port located at the throat of the venturi can be used to siphon another fluid.

A venturi is a constriction in a tube designed to cause a pressure drop when a liquid or gas flows through it.
