As you breathe, this contracts and flattens to give your lungs room to fill up with air:
|
|
larynx
|
|
|
lung balloon
|
|
|
diaphragm
|
|
|
bronchiole
|
Explanation:
Detailed explanation-1: -When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.
Detailed explanation-2: -The diaphragm and intercostal muscles both relax when exhaling. This allows the lungs to contract by means of their own elastic recoil forces so that the thorax returns to its original size and the air inside the lungs is gently exhaled.
