Solution

Diaphragm and intercostal muscles are the muscles which help in inspiration of air. During inspiration the diaphragm contracts pulling the floor of thoracic cavity inferiorly. By doing this it creates a vaccum which can be used to fill the inhaled air. The intercostal muscles elevates lungs during inspiration, thus helps the inhaled air get inside the lungs.
