In rats, the ribcage plays a crucial role in the process of gas exchange by facilitating the expansion and contraction of the thoracic cavity during respiration. When the diaphragm contracts, the ribcage elevates due to the action of intercostal muscles, increasing the volume of the thoracic cavity and creating a negative pressure that draws air into the lungs. During exhalation, the ribcage relaxes, decreasing the thoracic volume and pushing air out of the lungs. This mechanical movement aids in the efficient exchange of oxygen and carbon dioxide in the alveoli.
Gas exchange is a function of respiration not digestion.
The spongy layer in plant leaves helps with gas exchange, allowing for the exchange of carbon dioxide and oxygen during photosynthesis.

Gas Exchange
The primary function of alveoli is to facilitate the exchange of oxygen and carbon dioxide between the lungs and the bloodstream during the process of respiration. They are small air sacs located at the end of bronchioles in the lungs where this gas exchange takes place.
