Exempel på hur man kan använda EXHALANT i en mening

• The mantle has three apertures (inhalant, exhalant, and pedal) for siphoning water and for the foot to protrude.
• Oreaspis differs from Protaspis in ornamentation, and that the postbranchial plate (the plate posterior to the exhalant opening of the animal's gills) forms a tiny, wing-like process.
• Most are closely coiled with some general more openly coiled, cyrtiform; predominantly with a median slit in the upper lip of the aperture, or with a series of openings known as tremata, usually generating a selenizone which was probably exhalant in function.
• It has retractable inhalant and exhalant siphons which project through a small hole in the horny septum which blocks the opening of the burrow.
• Dagger-shaped small tetractines (pugioles) are frequently the sole skeleton of the exhalant aquiferous system.
• They are generally characterized by concentric layers of fibers containing spongin (a collagen-like material), and by large flagellated chambers that open directly into the exhalant canals.
• Groups of zooids tend to form pairs of parallel chains; each zooid has its own inhalant siphon but the groups share an exhalant siphon.
• Bivalves have two siphons or apertures at the posterior edge of their mantle cavity: an inhalant or incurrent siphon, and an exhalant or excurrent siphon or aperture.
• It is umbilicate or imperforate, having a deep slit or sinus in the outer superior margin of the peristome, which serves the purpose of an exhalant phase of respiration.
• Sea squirts are named for their habit of squirting a stream of water from their exhalant siphons when touched at low tide.
• Each zooid draws water into its interior through the inhalant siphon at the top and expels it through the exhalant siphon.
• Water enters the mussel's mantle cavity through the inhalant aperture, and after describing a series of movements during which suspended particles are filtered out and either ingested, digested in the gut, and the undigested remains egested as feces, or discarded as pseudofeces, is expelled through the exhalant siphon.
• Sea squirts are named for their habit of squirting a stream of water from their exhalant siphons when touched at low tide.
• Much of the internal space in the cyphonautes is devoted to a funnel that, in Membranipora
• Each zooid has a sac-like body with two siphons: an inhalant siphon that draws in water and food particles, and an exhalant siphon that expels waste and water back into the surrounding environment.
• The oscula (exhalant openings) are slightly raised and the pores (inhalant openings) are few in number but quite noticeable.
• in length, opening into wide exhalant canals, which interdigitate with the main inhalant canals running in from beneath the dermal cortex.
