Final answer:
Inhalation and exhalation are two different processes involved in breathing. During inhalation, air is taken into the lungs, while during exhalation, air is released from the lungs. The diaphragm and rib muscles play a crucial role in these processes.
Step-by-step explanation:
Inhalation and exhalation are two different processes involved in breathing. Inhalation refers to the intake of oxygen-rich air into the lungs, while exhalation is the release of carbon dioxide-rich air from the lungs. During inhalation, the diaphragm and rib muscles contract, expanding the chest cavity and creating a vacuum that allows air to flow into the lungs. On the other hand, during exhalation, the diaphragm and rib muscles relax, causing the chest cavity to decrease in size and expel the carbon dioxide-laden air out of the body.
