The rib cage expands, causing a negative pressure change in the abdominal cavity, which can only be relieved by letting air in the lungs. Exhaling is the opposite: the rib cage contracts, causing a positive pressure change, which is relieved by expelling air from the lungs.
The spongy layer in plant leaves helps with gas exchange, allowing for the exchange of carbon dioxide and oxygen during photosynthesis.
The organelle responsible for gas exchange in plants is the chloroplast. Carbon dioxide enters the chloroplast, where it is converted into oxygen during photosynthesis. In animals, the lungs are responsible for gas exchange, where oxygen is taken in and carbon dioxide is released.
The alveoli are small air sacs in the lungs where oxygen is taken up by the blood and carbon dioxide is released from the blood into the lungs to be exhaled. This gas exchange process is essential for respiration and providing oxygen to the body's tissues.
Type 2 alveoli cells secrete surfactant, which helps to reduce surface tension in the alveoli. This allows for easier expansion of the alveoli during inhalation and prevents them from collapsing during exhalation, promoting efficient gas exchange.
Leaves have small openings called stomata on the underside of the blade. Stomata function in gas exchange.
Gas exchange is a function of respiration not digestion.

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.
