Answer 1

ANSWER.

   * Three causative factors of both emphysema and chronic bronchitis.

             * Smoking.

                    Cigarette smokes damages the alveolar sacs and other

                    tissues in the lung which result in increased amount of

                    mucus production and shortness of breath.

                    Injuries occur in the air sacs affect the normal functioning of

                    lung and leads to emphysema.

                    Partial or complete obstruction of airways by excess mucus

                    leads to chronic bronchitis.

             * Polluted air.

                    Inhaling polluted air which contain toxic chemicals and dust leads

                    to inflammatory changes in the lungs and increased mucus production

                    result in both emphysema and chronic bronchitis.

             * Use of psychoactive drugs ( eg; Cannabis.)

                    Cannabis or marijuana is a psychoactive addictive drug and inhalation of

                    smokes of this drugs result in irritations in the airway and overproduction

                    of mucus and inflammatory changes which leads to emphysema and chronic

                    bronchitis.
