اس pdulmehum philum kainodermetake representative c stars ke under gashiyas sqsthange ke process ko discuss karengi. gashiyas, new trends, metabolic ways, joke c star ke body me produce honge, they are transported in the silom with the help of a mechanism known as diffusion. and by the action of siliated cells that are lining the body cavity. gashiyas, or joke excretion have metabolic ways ki principally, joke a animals they are living in marine water, so aquatic condition may jome metabolic ways, and mostly it is ammonia. this will takes place by the process of diffusion across the dermal brink eye, tube feet and other membrane structures that are present in the body of the c stars. abu respiration hai, you gashiyas, gashiyas, these occurs in two locations in c stars. first location you have that is through the skin, skin you have skin there, thin hai on the ends of the tube feet of gashiyas, change also occurs in the dermal gills or the papule. abu ye gills do hai, they are lined with silia, silia will move to produce a current. abu ye ju current hai, this brings the fresh water so that c star can absorb oxygen from that water, into the surrounding water that enters the body through the med riparide, or just they take out the carbon dioxide produced inside the body of the animal, along with the water that is moving out the body. is ki lava gashiyas exchange main, dhushra system help krta hai, despite the fact diffusion is taking place and there is a exchange of gases, but there is another system in the body of c stars that is helping in this gashiyas exchange process, hush system ko humkai ngayi, hemal system. abu ye hemal system ju hai, this consists of strands of tissues that are encircling the mouth, near the ring canal and then they extend aborally near the stone canal and run into the each arm near radial cana. Through this diagram we can elaborate this gas exchange in starfish, there are two mechanisms through which this process of gas exchange will takes place, one is through the thin skin, here is thin skin that is at the tube fit, water will enter, when water is entering the mouth, it is carrying the oxygen, as this water outside the body of the starfish will have a lot of oxygen, this oxygen will enter into the body and when the water leaves the body, this will take out the carbon dioxide that is produced inside the body, as a result of metabolic exchange, another is through the gills, these gills they are also helpful in gashiyas exchange in starfish.
