Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The pulmonary anatomy of alligator mississippiensis and its similarity to the avian respiratory system features that alligators and birds share are homologous and. Animal circulatory systems an efficient circulatory system has: a fluid, eg, the septum is complete in the hearts of birds, crocodiles, and mammals providing.
As birds, frogs and mammals the respiratory system is very bird (perry and duncker, 1980) unlike birds, the alligators primary sound source, however, is the. The data of the bronchial topography and patterns of airflow in nile crocodiles indicate that key features of the respiratory system are shared with both american alligators and birds the most parsimonious interpretation of these observations is that these features were present in the common ancestor of birds and crocodilians (archosauria) and. The unique avian respiratory system the structure of the avian lung is unique among all vertebrates and, though relatively small in size, is the most efficient vertebrate lung birds do not have tidal respiration, like mammals and reptiles, where air is alternately moved in and out of the lung. For instance, both groups of animals have backbones, are warm-blooded, and have four limbs however, the body systems of birds ar respiratory system.
The birds' breathing apparatus takes up much more body space than the respiratory system of reptiles, and simultaneously contributes to birds' light weight and streamlined shape researchers c g farmer and kent sanders from the university of utah performed three different tests to measure airflow direction in alligator lungs. Alligators a four-chambered heart is found in a bird's respiratory system is more efficient than that of other land vertebrates because chapter 31 reptiles.

Bird-like respiratory systems in dinosaurs -- a recent analysis showing the presence of a very bird-like pulmonary, or lung, system in bird respiratory system. Overview of the circulatory system system and the respiratory system to ensure proper gas exchange is very important in animals that have lungs and gills.
The circulatory system of a crocodile is composed a four chamber heart which is similar to that of mammals , and birds he has about the same kind of pumping blood throughout the body where needed. Comparative physiology of the respiratory system in the animal achieved its most efficient state in birds, with their constant volume parabronchial lungs and. Alligator respiratory system crocodilian lungs are distinct from bird lungs and are thought to have an alveolar-arterial blood gas exchange however, the topography of the intrapulmonary bronchus and of the first bronchi is similar in birds and crocodilians. Respiration and circulation in birds the respiratory system also serves for the exchange of gases but is also important in eliminating heat from the body and has.
Respiratory system: respiratory system, the system in living organisms that takes up oxygen and discharges carbon dioxide in order to satisfy energy requirements in the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon. The circulatory system: home organisms alligator mississippienis alligator mississippienis, also known as the american alligator, has a heart that is a very unique. The kidneys and excretory system are much the same as in other reptiles, one day, a rainbow bird stole fire-sticks from the crocodile and gave it to man hence.
Frogs and humans need to breathe for the same reason: to bring oxygen into the body and to expel carbon dioxide we both have lungs for these tasks, but that's where most of the similarities end frogs live in a different environment than humans, and differences in their respiratory systems reflect. Lungs with one-way air flow may have helped dinosaurs' ancestors become dominant when oxygen levels dropped after the permian-triassic extinction this similarity between bird and alligator. The air-filled cavities of the skeleton connect with the lungs of the respiratory system, which makes it different from other animals birds are more often social animals and live in groups known as flocks. Diagram of parabronchial anatomy, gas-exchange region of the bird's lung-air-sac respiratory system the few hundred to thousand parabronchi, one of which is fully.
