name the breathing organs of fish, tortoise, shark, whale, octopus
Answers
Answer:
Explanation:
1)gills
Fish and other aquatic organisms use gills to take up oxygen dissolved in the water and diffuse carbon dioxide out of the bloodstream.
2)The trachea splits near the heart into two bronchi that deliver air to the lungs, where it is absorbed into the body. Since a turtle's shell cannot expand and contract the way a person's ribs do, turtles have muscles inside their shells that expand and contract to move air in and out of the lungs.
3)gills
Like other fish, sharks "breathe" through their gills, which are respiratory organs akin to our lungs. As water passes over the gill's membranes, tiny blood vessels extract oxygen from the water. Carbon dioxide waste also passes from the shark's blood and out of its body through the gill tissue.
4)Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
5)The gills allow an octopus to breathe in oxygen and then exhale through a tube called a siphon. If an octopus breathes fast and exhales hard, it can swim backward by jet propulsion.
Explanation:
answer
Gills are the respiratory organs in aquatic organisms such as fishes. Gills help in the exchange of respiratory gases by absorbing dissolved for fish
