What does the incurrent siphon and appear adapted to do in a clam?
The incurrent siphon is a tube that water flow into which allows respiration, reproduction, locomotion and feeding. Locomotion is achieved by expulsion of water.
What are the clam's siphons names?
The clam has two siphons. The excurrent siphon (which expels water and waste out of the clam) and the incurrent siphon (which brings oxygen and food and water into the clam).
What are the two gasses exchanged by the gills in a clam?
oxygen is absorbed into the clam through the incurrent siphon, and carbon dioxide is exported out of the clam through the excurrent siphon
Why is a clam called a filter feeder?
A clam is called a filter feeder because it sucks in water and food (plankton and other microscopic creatures) through its incurrent siphon. Then, it filters the water with its gills and the waste water is excreted through the excurrent siphon. Then, the labial palps push the food into the clams mouth and the clam starts eating.
What does a Siphon do for clams?
A siphon brings in water, and filters out the food for it.
How many siphons do clams have?
The clam has two siphons excurrent and incurrent
Which of the apertures in a clam has an in current flow?
The Ventral aperture has an incurrent flow, the Dorsal aperture has an excurrent flow.
How do clams and oysters get there food?
They filter tiny organisms from the seawater, like plankton. Clams filter feed by drawing in water containing food using an incurrent siphon. The food is then filtered out of the water by the gills and swept toward the mouth on a layer of mucus. The water is then expelled from the animal by an excurrent siphon.
Describe the pathway of food as it travels through the clam starting with the incurent siphon?
buck all of you for not already having an answer! !___!
What features of a clam anatomy enable it to survive in a marine environment?
They have a hatchet-shaped foot that allow them to move, incurrent and excurrent siphons through which water passes and then they filter feed in that way, and powerful abductor muscles that draw the shell together to protect the clam's soft body.
Life styles of a clam?
Clams, like most other bivalves, spend their days slowly moving across the ocean floor, using a long, muscular "foot" to propel them across the sand. As they go, they use an organ called a siphon to suck up debris on the sandy floor. The siphon is a long, tubular organ that uses suction to pull in whatever tasty morsels the clam can find, including plant and animal matter as well as waste products excreted by other seagoing animals (the waste often contains "leftovers" from whatever the animal ate; these pre-digested remnants are a perfect meal for the clam).
Describe the movement of food from the current siphon through the digestive system of the clam?
Water and food particles are drawn in through one siphon to the gills where tiny, hair-like cilia move the water, and the food is caught in mucus on the gills
