Which of the following are symptoms of emphysema?Check All That ApplyThe elastic recoil of the lungs is reduced.The elastic recoil of the lungs is reduced.The surface area for gas exchange is reduced.The surface area for gas exchange is reduced.The alveoli are distended and their walls damaged.The alveoli are distended and their walls damaged.There is less stress on the heart to pump blood through the lungs.There is less stress on the heart to pump blood through the lungs.

4) Which of the following will increase alveolar PO2?a) increase in metabolism and no change in alveolar ventilationb) breathing air with 15% oxygen at sea levelc) increase in alveolar ventilation matched by an increase in metabolismd) increased alveolar ventilation with no change in metabolisme) carbon monoxide poisoning

Q15. The most powerful respiratory stimulus for breathing in a healthy person is ________.a) loss of oxygen in tissuesb) increase of carbon dioxide in bloodc) decrease of oxygen in bloodd) increased muscle activity

Which of the following statement(s) is(are) true regarding exhalation? Question 26 options: there is a decrease in both the lung volume and pressure in the lungs there is a increase in the lung volume and diaphragm moves downward there is a decrease in lung volume and the diaphragm moves downward there is a decrease in lung volume and the diaphragm moves upward there is a increase in the lung volume and the diaphragm moves upward

Given your understanding of how healthy lungs work, describe how emphysema disrupts the exchange of oxygen and carbon dioxide between the air and blood.
