Discuss the pathway of air through the respiratory system of vertebrate
Step by step
Solved in 3 steps
- Figure 39.7 Which of the following statements about the mammalian respiratory system is false? When we breathe in, air travels from the pharynx to the trachea. The bronchioles branch into bronchi. Alveolar ducts connect to alveolar sacs. Gas exchange between the lung and blood takes place in the alveolus.Discuss briefly other function(s) of the respiratory structures aside from the primary function of gas IN ANIMALSDiscuss Tidal, residual, minimal air in Gaseous Exchange in Animals
- When considering the limitations of external respiration, explain why animals larger than flatworms require specialized structures for ventilation. List two examples of these specialized structures.Differentiate the Pulmonary volumes and pulmonary capacities in animal physiology.Describe structural and functional differences between gills and lungs (ie. know the anatomy of lungs and gills). Why are birds’ lungs more efficient at removing O2 from the air compared with mammalian lungs?
- Outline the differences among the three most sophisticated lungsfound in modern animals: the mammalian lung, the avian lung,and the insect tracheal system.Discuss the importance of the contraction and relaxation of the mammalian diaphragm in breathing.Compare the avian and mammalian lungs in terms of structure and respiratory function
