                    diseases:
                    (a)  asthma;                      13.  How do different environmental
                                                            conditions, such as altitude or
                    (b)  lung cancer;                       pollution, affect the efficiency
                    (c)  pneumonia; and                     of gas exchange in the lungs?

                         (COVID-19)                   14.  In what ways do you think the
                                                            structure of alveoli contributes to

              9.    How does the structure of alveoli       their function in gas exchange?
                    maximize gas exchange?            15.  What might happen to a living

              10.  Differentiate between                    organism if its gas exchange
                                                            system is compromised, and
