Both gills and lungs are formed from outpouchings of the gut wall during embryogenesis. Such structures have the advantage of a protected internal location, but this requires some sort of pumping mechanism to move the external gas-containing medium in and out.

What are 2 differences between a lung and a gill?
What is the difference between Gills and Lungs? Both organs are vital as gas exchanging surfaces, but gills are important to extract dissolved oxygen in water while lungs are important to extract atmospheric oxygen. Gills are found in aquatic organisms, whereas lungs are found in terrestrial air-breathing animals.
What are the similarities between human and fish respiratory systems?
The respiratory system of fish and humans are very different, however they are similar in that both organisms intake oxygen through their mouths, and exhale carbon dioxide. Internal respiration is when gases in the form of oxygen and carbon dioxide are exchanged between the cells of the body and the blood.
What is common between all respiratory organs?
(i) All the respiratory organs have large surface areas to get enough oxygen. (ii) All the respiratory organs are thin-walled for easy diffusion of gases and substances. (iii) All the respiratory organs (like skin, lungs, gills) have a rich supply of blood for transporting respiratory gases.
What do all respiratory systems have in common?
A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
What animals have both lungs and gills?
Lungfish have a unique respiratory system, having both gills and a lung. It is the only type of fish to have both organs, and there are only six known species around the world.
How do lungs and airways compare among birds and mammals?
The mammalian lung has reciprocating ventilation with large terminal air spaces (alveoli) while the avian lung has a flow-through system with small air capillaries. As a result the environment of the pulmonary capillaries is very different between the mammals and birds.
Can gills breathe air?
We inhale air, use the oxygen and breathe out carbon dioxide. Fish use gills to "breathe" by dissolving the oxygen from the water into their bodies. ... Fish need the water so they can dissolve the oxygen to "breathe", whereas humans need air (and the high oxygen concentration of the air) to inhale their oxygen content.
How did gills evolve into lungs?
Gills were present in the earliest fish, but lungs also evolved pretty early on, potentially from the tissue sac that surrounds the gills. Swim bladders evolved soon after lungs, and are thought to have evolved from lung tissue.
Why are gills external and lungs internal?
Answer: Gills are external since they need to be in contact with water for O2 to diffuse efficiently. Lungs are internal to prevent them from drying out which affects gas exchange.
What is the difference among gills book lungs and lungs?
Although they have a similar book-like structure, book gills are external, while book lungs are internal. Both are considered appendages because book lungs develop from limb buds before the buds flatten into segmented lamellae.
Which organ in the fish is most similar to the human respiratory system?
Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.
Which organ is the fish most similar to the human lungs?
Like us, fish also need to take in oxygen and expel carbon dioxide in order to survive. But instead of lungs, they use gills. Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries.
What are the similarities and differences between gas exchange in mammals and fish?
Mammals and insects both get their oxygen from air, while fish get oxygen from water. Water has a much lower oxygen concentration than air, and is harder to ventilate because it is more viscous. This means fish need to have a more efficient gas exchange system to get enough oxygen from the water.
