Reptilian lungs are typically simpler and less efficient than mammalian lungs, featuring fewer alveoli and a more limited surface area for gas exchange. Reptiles often rely on a more rigid lung structure, using muscle contractions to facilitate air movement, while mammals have a diaphragm that allows for more effective inhalation and exhalation. Additionally, mammalian lungs have a more complex branching system that enhances oxygen absorption. Overall, these differences reflect the varying respiratory needs and evolutionary adaptations of reptiles and mammals.
none it was a dino stupid people
There's a misconception at work here. The reptilian branch of evolution did not spawn the mammalian branch of evolution. You need to go back to the reptilian ancestor that was also a mammalian ancestor. We humans do have what is referred to as a reptilian brain, which is a small part of our whole brain.
Reptile lungs do not contain alveoli in the same way that mammalian lungs do. Instead, reptilian lungs are typically structured with a series of air sacs or chambers that facilitate gas exchange. Some reptiles have a more complex lung structure with infoldings to increase surface area, but they lack the alveolar system found in mammals. As a result, while they can effectively exchange gases, their respiratory system is different from that of mammals.
A mammal's brain is about 15 times heavier than the brain of a similarly sized fish, amphibian, or reptile.
Dolphins have a mammalian respiratory system, ie. lungs.
the lungs
smaller
Yes, bearded dragons have red blood cells. Reptilian red blood cells are different to mammalian red blood cells in that they have a nucleus and are oval in shape.
lungs are vertical to the spine
Lungs do not differ that much in domestic animals. These animals need oxygen just like the animals that are in the wild.
Amphibious
Mammalian brains evolved from reptilian brains (simply instinctive), develop feelings and can alter instincts through experience.
