After 2 hours' respiration by the gills in fresh water, the water was replaced by water of a known salinity and the respiration rate was measured for 20 hr. The clam has a pair of very large gills, and the surface of the gills is covered with cilia. 16. 19. Where are the palps found and what is their function? 14. 12. Cilia on gills. Describe the movement of food from the current siphon through the digestive system of the clam. What is its function? What helps direct water over the gills? How do clams breathe? 9. The cilia beat in a coordinated fashion, and the movement of the cilia cause water to move into and through the clam. How do clams breathe? The sex glands help the water over the gills which causes the clam to have an orgasm and then have and erection. It helps with locomotion in any direction by "spitting" out a stream of water. They use feathery gills for respiration (gas exchange), as oxygen diffuses into the gills. What helps direct water over the gills of a clam? Cilia on gills 13. What is the mantle cavity? 11. 14. 21. ... Water Flow •Incurrent siphons aid in bringing in water with food and oxygen •Cilia direct water into the gills, while labial palps direct water into the mouth Cilia on the gills pulls in water move food toward the Mussels breathe exclusively with gills. 20. 9. Each point ( in Fig. 11. Describe the movement of food from the current siphon through the digestive system of the clam. A pair of labial palps are located at the anterior end of each set of gills. A squid's siphon is multi-functional. These data together suggested aberrant changes occurred in the metabolomics profiles of the Manila clam under the stress of hypoxia. The results are shown in Figs. Where is the clam's heart located? What is the function of the tooth-like projections at the dorsal edge of the clam's valves? What helps direct water over the gills? How do clams breathe? Where are the palps found and what is their function? Rather than breathing in and out through the mouth, fish use a one-way system, passing water in one direction over their gills. They direct the trapped food toward the mouth. It also gets rid of other internal waste. The gills not only serve for respiration, but also for feeding the mussel. 10. 10. 3 represents the mean respiratory rate of the gills over the first two hours in the same medium. What helps direct water over the gills? 12. Where are the palps found and what is their function? 13. Where is the clam's heart located? while freshwater clams are smaller (3/4 inch) ... flows over them Gills copyright cmassengale. 8. Where is the mantle located in the clam? Where are the palps found and what is their function? the anterior end of each set of gills. Food-containing water enters through the incurrent siphon and passes over the gills. Where are the palps found and what is their function? Describe the clam's foot. 18. 3I). Why are clam's … Their function to direct the trapped food toward the mouth. In different bivalve groups the gill construction can be so different, that the gill construction type is a major part of bivalve systematics. What helps direct water over the gills? It helps the squid breathe by getting rid of the "wastewater" from the seawater pumped over the gills in the mantle (head). What helps direct water over the gills? 17. In addition, a late accumulation of aspartate in the clam gills (6.33 μmol g − 1 wet tissue) was observed on the 20th day of hypoxia exposure, with a 40% increase over the control group (Fig. 3 and 4.
