The breathing process for sharks begins and ends with their gills, which they use to both extract oxygen from water and rid their bodies of carbon dioxide. Here's the quick version of how it works, according to Sharkopedia: As water passes over the gills, small capillaries allow oxygen to enter the bloodstream.

How do gills help sharks survive?
Sharks, like other fish, live in the water and use their gills to filter oxygen from the water. When water passes over the gills, a system of very fine blood vessels (capillaries) in the gills takes up (absorbs) oxygen from the water. ... Water must continually flow across these slits in order for the shark to breathe.
How do gills of fish help their survival?
As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water. ... That means fish need to run a lot of water over their gills to get the amount of oxygen they need to survive. Also, gills are very efficient in extracting the oxygen the fish needs!
What is the function of gills?
Gills are evaginated respiratory surfaces used for breathing in water. Gills are present in all amphibian larvae and in some aquatic salamanders. They are typically highly branched structures.
What do sharks gills?
Gills allow fish to take in oxygen from the surrounding water and eliminate carbon dioxide from the blood. Sharks can have up to seven external gill openings, but most species have five. Gill arches are considered part of the skeleton; they hold the gills in place. The arches support one or two rows of gill filaments.
How do sharks breathe through their gills?
As sharks swim water passes through their mouth and is pushed through their gills. The gills filter the oxygen out of the water. The oxygen is then passed into the blood and travels around the shark's body. ... This is how a shark breathes underwater.
Can sharks survive without fins?
The sharks are often still alive when discarded, but without their fins. Unable to swim effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. ... Some countries have banned this practice and require the whole shark to be brought back to port before removing the fins.
How do gills help fish maintain homeostasis?
Certain fish, such as sharks and tuna, can control their body temperature using a paired blood vessel system, where warm blood going to the gills swaps heat to colder blood coming back from the gills, thereby keeping a higher blood temperature than pure poikilothermic fish.
How do fishes breathe underwater?
How do fish breathe? ... With most—but not all—fish, the gills do the same thing. Fish take water into their mouth, passing the gills just behind its head on each side. Dissolved oxygen is absorbed from—and carbon dioxide released to—the water, which is then dispelled.
Do sharks have gills?
The breathing process for sharks begins and ends with their gills, which they use to both extract oxygen from water and rid their bodies of carbon dioxide. ... As water passes over the gills, small capillaries allow oxygen to enter the bloodstream.
What other functions might gills support?
Gills in most aquatic animals, including fish, have many other functions apart from gas exchange and may include feeding, excretion of water-soluble waste, acid-base balance and control of body electrolytes.
What is the purpose of gills in fish Class 10?
The gills are the organs that help the fish to undergo the process of respiration under the water.
Which animal breathes through gills?
Animals that live in water breathe through gills with very few exceptions. Aquatic animals with gills include fish, prawns, amphibians, arthropods, worms, whale sharks, big blue octopuses, giant calm, etc.
What does shark need to survive?
Sharks are carnivores, and they primarily hunt and eat fish, sea mammals like dolphins and seals, and other sharks. Some species prefer or include turtles and seagulls, crustaceans and mollusks, and plankton and krill in their diets. ... Sharks need to keep water moving over their gills to receive necessary oxygen.
What are sharks gills called?
Gill slits are individual openings to gills, i.e., multiple gill arches, which lack a single outer cover. Such gills are characteristic of cartilaginous fish such as sharks and rays, as well as deep-branching vertebrates such as lampreys.
Where are a sharks gills?
All sharks have five to seven pairs of gills on the side of the head. Gas exchange occurs at the gills and oxygenated water must always be flowing over the gill filaments for respiration to occur. Water enters through the mouth of the animal, into the pharynx, over the gills and exits through the gill slits.
What helps a shark breathe?
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.
Can sharks breathe without moving?
As fish, sharks cannot hold their breath. They get oxygen from water passing over their gills. Answer: Yes for most species (barring unusually strong currents), but not all. Many species of sharks do indeed need to be constantly moving forward their entire lives so they can breathe!
Can sharks survive without water?
There are many different sharks and some have evolved to live outside of water for a few minutes, but most large shark species, such as the great white or tiger shark can only survive minutes up to 11 hours outside of water before they die. ... The sharks suffered from dehydration and soon died.
