Students have asked these similar questions
1. What is the significance of the alveoli in the respiration of toad/frog? Answer it comprehesively and do not just copy from somewhere, please.
Learning Task 1: Study the diagram of the human respiratory system. Copy the diagram and label the parts correctly. Choose form the words listed below.
14. Trace the route of inspired air in humans from the nostrils to the smallest chamber of the lungs. What is the "dead air space" of a mammalian lung and how does it affect the partial pressure of oxygen reaching the alveoli? How is this problem partially solved by bird respiratory system?
16. How does a frog ventilate its lungs? Contrast an amphibian's positive-pressure breathing with a mammal's negative-pressure breathing.
