____________  increases back toward its preinspiration value.

____________  becomes greater than  ____________ .

The  ____________   and inspiratory intercostal muscles stop contracting, causing the  ____________  to recoil inward.

Explanation / Answer

The transpulmonary pressure increases back towards the inspiration value.

The diaphragm and inspiratory intercoastal muscles stop contracting causing the chest wall to recoil inward

The alveolar pressure becomes greater than atmospheric pressure

The intra pleural pressure moves back towards pre inspiration value allowing the lungs to passively recoils towards pre inspiration size

Air in the alveolar sacs become compressed

Air flow out of lungs.
