The Litoria caerulea (Green tree frog) has a very unique respiratory system that is very different to the Homo sapiens (Humans). The respiratory system is made up of organs in your body to help you breath by delivering oxygen to the body and expelling carbon dioxide. The respiratory system consists of Lungs, Diaphragm, Bronchi and Trachea along with others. These organs have crucial roles in the process of respiration (the act of breathing) (Hillendale Health, Hes.ucfsd.org, 2014). However, the frogs have other organs such as the skin & mouth as well as lungs that play a role in respiration. I will discuss a detailed explanation of the respiratory system in each species, how alveoli have a role in respiration as well as explaining …show more content…
At the end of each alveolar duct there are number of sac-like structures called alveoli. The alveoli are grouped together like interlinked caves (Shown in Figure 3). “Oxygen from inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. Oxygen is then carried by the blood to the body tissues. Carbon dioxide produced by the body returns to the lung via the blood, it then diffused across the capillary and alveolar walls into the air to be removed from the body. The alveoli has a structure specialised for maximum gaseous exchange, Walls are thin” and fluid lined enabling gas to dissolve through walls easily, surrounded by capillaries and has a large surface area achieving maximum oxygen intake.(Curoservice.com ,2014). Alveoli in humans are more densely packed than frogs as humans rely exclusively on their lungs to breathe (Animals-PawNation, …show more content…
Where humans use a diaphragm and frogs utilize mouth, nostrils and skin, there a various unique ways animals can extract oxygen.
In conclusion the human and the frog have similarities within their system. They both require oxygen; their systems both consist of bronchi tubes, lungs, alveoli and nostrils. Small differences such as the density of the alveoli and the more complex bronchial tubing in the Homo Sapian. More differences include Humans only using lungs controlled by the diaphragm, where frogs use their skin, moist lining of mouth, muscles under jaw and
