Select from the dropdown lists to complete the text.

During inspiration the ( external intercostal, internal intercostal ) muscles, ( contract, relax ) bringing the ribcage up and outwards. The diaphragm contracts moving ( down, up ). This ( increases, Decreases ) the thoraic cavity's volume and the lungs expand. This decreases the presure inside the lungs. The air therefore moves ( into, out ) the lungs.
