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.

How are gills and lungs similar?
Gills. ... While lungs breathe in oxygen from the air, gills get oxygen from water. Gills are external while lungs are internal. Since fish live in water it's obvious their lungs are structured different and work differently than human lungs.
Are lungs and gills the same thing?
Gills are found in aquatic organisms, whereas lungs are found in terrestrial air-breathing animals. Gills are able diffuse excretory products but not the lungs. Gills could be either interiorly or exteriorly located organs, whereas lungs are only interior organs.
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 the relationship of gills and breathing?
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.
Can you have gills and lungs?
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 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.
What are gills?
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.
What is breathing through gills?
Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages. As water passes over the thin walls of the gills, dissolved oxygen moves into the blood and travels to the fish's cells.
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.
What is the difference between fish and human respiratory system?
Lungs in humans and gills in fish use blood capillaries to remove the oxygen they need and excrete waste carbon dioxide. Fish have adapted to absorb oxygen from the water they filter, whereas humans and insects on land diffuse air which is easier and more efficient.
What characteristics can you observe in the gills that make them an efficient respiratory organ?
Gills are very efficient at removing oxygen from water: there is only 1/20 the amount of oxygen present in water as in the same volume of air. Water flows over gills in one direction while blood flows in the opposite direction through gill capillaries. This countercurrent flow maximizes oxygen transfer.
What are physical gills?
Physical gills are a type of structural adaptation common among some types of aquatic insects, in which atmospheric oxygen is held within an area into which the spiracles open. ... The physical gill mechanism allows aquatic insects with plastrons to remain constantly submerged.
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.
How do invertebrates breathe?
Many aquatic invertebrates take oxygen directly from the water through internal or external gills, directly through the skin, or through the use of a bubble of air which is attached to their bodies and which they take with them below the water's surface.
