  • Respiration. The diaphragm is a sheet of muscle separating the chest cavity from the abdominal cavity which, when relaxed, domes upwards; on breathing in the diaphragm contracts & flattens down, thus increasing the capacity of the chest, and causing air to be drawn into the lungs.
  • When the diaphragm contracts that causes the volume of the lungs to increase. When the lung volume increases, the air pressure drops causing air to come in from outside (inhaling). When the diaphragm relaxes, the process is reversed. Lung volume decreases, air pressure builds, and air is forced out (exhaling).
