L_0730 | pressure of fluids | T_3618 | FIGURE 15.6 This graph shows how air pressure de- creases with increasing altitude. the air pressure on the surface of the drink. Because fluid flows from an area of high to low pressure, the drink moves up the straw and into your mouth. When you breathe, a muscle called the diaphragm causes the rib cage and lungs to expand or contract. When they expand, the air in the lungs is under less pressure than the air outside the body, so air flows into the lungs. When the ribs and lungs contract, air in the lungs is under greater pressure than air outside the body, so air flows out of the lungs. | image | textbook_images/pressure_of_fluids_22296.png |
L_0730 | pressure of fluids | T_3618 | FIGURE 15.7 Both drinking through a straw and moving air into and out of the lungs is possible because of differences in air pressure.
