Which of the following statements is correct about the process of breathing in the MAMMALIAN Respiratory System? Strong contraction of the Diaphragm exerts a positive force on the Trachea and Bronchioles, which pushes air into the lungs through positive pressure. Breathing with Lungs must be more efficient than breathing with Gills, since atmospheric air has less oxygen available, when compared to the amount of oxygen dissolved in water. During Inhalation, contraction of the Rib Muscles and Diaphragm increases the volume...
