incurrent การใช้

• Each clam then fills its water chambers and closes the incurrent syphon.
• There is an inhalant or incurrent siphon, and an exhalant or excurrent siphon.
• Sperm is released by the male directly into the water and enters the female via the incurrent siphon.
• The gill cilia draw in water through the incurrent chamber and run posteriorly in the excurrent stream where they are discharged.
• It is estimated that water enters through more than 80, 000 incurrent canals at a speed of 6 cm per minute.
• They are present in the Leucosolenia ( a asconoid sponge ) at the body wall through which water enters the body or they are present in Scypha ( a syconoid sponge ) as a connection between incurrent canal and radial canal.
• This can be described as the flow of water in a U-shaped course; water passes posteriorly from the incurrent opening, an opening in the carapace near the base of the chelipeds, dorsally over the gills, and anteriorly to exit beside the head.
