Inhalation (Inspiration) results from the contraction of the external intercostal muscles, in tandem with the contraction (flattening) diaphragm as well. This increases the volume in the thorax and hence lowers the pressure inside the lungs compared to the outside environment. Air moves from a region of high pressure to a region of low pressure and so the process of inhalation is complete.

What are similarities and differences between inhalation and exhalation?

Both inhalation and exhalation are part of the respiratory process where air is exchanged in the lungs. During inhalation, the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. During exhalation, these muscles relax, and the chest cavity decreases in size, forcing air out of the lungs. The key difference is the direction of airflow: inhalation is the process of taking air into the lungs, while exhalation is the process of expelling air from the lungs.


Is exhalation and inhalation known as cellular respiration?

No, cellular respiration is a biochemical process that takes place in cells to produce energy. Exhalation is the process of releasing carbon dioxide from the lungs, while inhalation is the process of taking in oxygen. They are related but not the same.
