In other mammals the eusophagus is different: The larynx is fixed at the top of the throat and can make a valve at the back of the nose to form a breathing tube parallel to the esophagus. Humans are speaking through the valve that is normally used to drink and breathe at the same time.
The nasal cycle is not only limited to the human nose, as it has been found in the rat and rabbit [31], the domestic pig [32, 33], the cat [34] and the dog [35], and appears to be a universal phenomenon at least in all mammals and possibly other animals. ...
Mammals typically cannot breathe underwater without assistance, as they require oxygen to survive, and their respiratory systems are adapted for breathing air. However, some mammals, such as ...
7. Insects breathe by simple diffusion through the cell walls. They do not breathe in the same sense that we humans do. They intake oxygen through spiracles in the insect's cuticle. It goes through the insect's trachea by dissolving into the tracheal liquid. From there it diffuses throughout the insect in tracheal tubes.
Fishes can breathe for much longer than a few hours under water as they spend their whole life underwater. Animals-with-lungs (such as most terrestrial mammals) All mammals, whether terrestrial (like a cow) or not (like a dolphin) have lungs. While all mammals have lungs, most fish (but not all) have gills. Lungs vs Gills
2. Some mollusks have lungs and can use breath for nest building, defense and diving. They have 100 times less neurons than arthropods. semi-aquatic insects can control air for going under-water, and some spiders, beetles and spittle-bugs can control bubbles. There are even shrimps that snap at water to produce bubbles.
As others have pointed out, we do breathe atmospheric nitrogen but we cannot do anything useful with it. The problem is that the triple-bonded N 2 is very unreactive and almost all animals and plants cannot convert it to anything else. Humans do not have the ability to reduce it to NH 3, for example, but is would be great if we could.
Updated: 10/8/2023. Wiki User. ∙ 7y ago. Best Answer. Wolves breath from their lungs (like us) breath from their nose (like us) and breath from their mouth,or snouts, or muzzles (like us) They ...
4. Another part of the answer is that it's probably a lot more difficult to re-evolve gills than to evolve the simple streamlining &c that is necessary to become air-breathing aquatic mammals. There'd also seem to be no real pressure/advantage, since air-breathing whales, dolphins and so on are pretty successful top-of-their-food-chain ...
Lions breathe through their nose and mouth, just like humans. Their respiratory system allows them to take in oxygen from the air and expel carbon dioxide as they breathe. Lions have a large chest ...
