Test Your Understanding 1. Which of the following is a benefit of gas exchange in air compared with gas exchange in water? (a) air has a higher concentration of molecular oxygen (b) oxygen diffuses more slowly in air (c) no energy is required for ventilation (d) moist respiratory surface is not needed (e) air is denser than water

How would paralysis of the diaphragm alter inspiration? It would prevent contraction of the intercostal muscles It would prevent inhalation because the intrapleural pressure would not change It would decrease the intrapleural pressure and allow more air to enter the lungs It would slow expiration because the lung would not relax.
