I think that this will be FAR in the future. Sounds like science fiction now.
dissolved oxygen in water that is absorbed by the gills.
Crabs have gills that extract oxygen from the water, allowing them to breathe underwater. They take in water through their mouths and absorb the oxygen through their gills, while releasing carbon dioxide back into the water.
Sea creatures breathe underwater using gills, which extract oxygen from the water. Gills are equipped with thin membranes that allow oxygen to pass through and carbon dioxide to be released. This process enables sea creatures to extract oxygen from the water in order to survive.
Gills in periwinkles are located inside their shell, specifically on the mantle cavity, which is a chamber located next to the body where water enters and exits. The gills are responsible for extracting oxygen from the water and expelling carbon dioxide.
Gills are a vital part of the respiratory system in fish and other aquatic organisms. Humans (and other mammals) have tiny air sacs in the lungs, alveoli, that are responsible for the exchange of gases to and from the blood. The same is true with fish, except their version of alveoli (gills) are external to exchange gases directly to and from the water. This allows for a process called "countercurrent exchange" by which oxygen is able to diffuse into the capillaries of the gills as the fish swims.Fish without gills is like you without lungs. The intake of oxygen and export of carbon dioxide can't be possible solely through integumentary diffusion in multicellular organisms.Fish have gills because they need to breathe in the water.They take the place of lungs, and permit fish to breathe oxygen from water.fish have gilles so that they can breath under water and also swim and breath at the same timefish have gills to breath underwater. They cant breath on land because gills are for breathing underwater and lungs are for breathing on land.People used to take baby puppies and drown them in the water. They did this because they wanted to see if they were able to survive in the water. So one puppy, by the name of Kelsey, was in the middle of being drowned, and it thought of its inner strength. It then began to shake and the water turned neon red! When the person who was drowning the puppy lifted it up, the puppy had gills and became quite scalish. Then the puppy swam away and it later mated with another fish and they made:GOLD FISHPEACE OUT
They use their gills to breathe under water.
No, no mammals don't have gills, and can't breathe under water. Mammals have lungs, breathe air and have to hold their breath when diving.
they have gills
well yes they do 'breathe' underwater with their gills
No, mammals don't have gills, and can't breathe under water. Mammals have lungs, breathe air and have to hold their breath when diving.
they may have gills
because humans do not have gills.
They have gills, wich are extremely blood-rich organs. Gills collect oxygen from the water so the animal can breathe.
all fish have gills. they have gills instead of lungs, so they can breathe under water. Whales and dolphins do not have gills because they are mammals.
They have gills under their mouths that allow them to breathe. When the gills start to dry out, foam forms at the mouth, telling you that the crab has trouble breathing.
Fish have gills so if it was out of water it will breathe through its mouth. The gills are used to breathe under water like sharks
dissolved oxygen in water that is absorbed by the gills.
