Answer:
The epiglottis is the flap-like structure. This is the covering above the trachea which prevents the entry of food in the respiratory system. This flap opens when the air is taken in and given out. This allows the air to move in and out of the tracheal system.
The diaphragm is the membranous structure in the abdomen. This structure becomes flat during inspiration which helps to increase the volume of the thoracic cage. This allows the air to be taken in the lungs. During the process of expiration, the diaphragm becomes dome-shaped. This reduces the volume of the thoracic cage and helps to pump the CO 2
out from the lungs.
