Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. The blood capillaries in the gill filaments are close to the gill surface to take up oxygen from the water and to give up excess carbon dioxide to the water. ...

What function do gills perform?
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.
How does respiration take place through gills?
Through Gills
Gills contain blood vessels which help in exchange of gases. Fish live in water. To get oxygen dissolved in water, fish gulp water through the mouth and pump it over the gills. Water passes into the gill chamber through gill slits.
What is the function of gills and lungs?
Gills and lungs are the two types of respiratory systems that occur in vertebrates. Their main function is to facilitate gas exchange. They are surrounded by blood vessels. They help to take oxygen from the outside environment while eliminating carbon dioxide to the outside.
Where is gills located in fish?
Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries. 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.
How does respiration take place in fish?
Respiration in fish takes place with the help of gills. Most fish possess gills on either side of their head. Gills are tissues made up of feathery structures called gill filaments providing a large surface area for exchange of gases. ... Fish take in oxygen-rich water via their mouths and pump it over their gills.
What animal breathes with gills?
gill, in biology, type of respiratory organ found in many aquatic animals, including a number of worms, nearly all mollusks and crustaceans, some insect larvae, all fishes, and a few amphibians.
What is gill respiration?
A gill (/ɡɪl/ ( listen)) is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist.
What is respiration in invertebrates?
Two common respiratory organs of invertebrates are trachea and gills. Diffusion lungs, as contrasted with ventilation lungs of vertebrates, are confined to small animals, such as pulmonate snails and scorpions.
Do frogs have gills?
When a frog egg hatches, a wiggly tadpole emerges that can live only in water. It breathes through gills. ... Their gills absorb oxygen directly from the water in which they swim, releasing waste carbon dioxide at the same time. As they mature, the gills are slowly absorbed, and primitive lungs begin to develop.
What are the respiratory organs of echinoderms?
Echinoderms have a a poorly developed respiratory system. They use simple gills and their tube feet to take in oxygen and pass out carbon dioxide.
Do whales have gills?
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. ... After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin's lungs.
Do shellfish have gills?
Larger aquatic crustaceans primarily use gills for respiration. These feathered surfaces contain membranes that bind to dissolved oxygen in the water as water passes over.
Do octopuses gills?
The reddish-brown body of the Giant Pacific Octopus consists of eight arms and a “mantle,” which extends from the head like a bag and has two sets of gills. ... The gills allow an octopus to breathe in oxygen and then exhale through a tube called a siphon.
Do dolphins have gills?
Dolphins are mammals, not fish.
Unlike fish, who breathe through gills, dolphins breathe air using lungs. Dolphins must make frequent trips to the surface of the water to catch a breath. The blowhole on top of a dolphin's head acts as a "nose," making it easy for the dolphin to surface for air.
What is Branchial respiration?
Branchial respiration is the type of respiration which occurs through gills. For example -respiration in fishes. [Respiration through lungs is known as pulmonary respiration]
Do amphibians breathe with lungs or gills?
Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die).
