The two kinds of muscles involved with breathing are:
-
Diaphragm: This is the primary muscle used in the process of inhalation. It is a dome-shaped muscle located at the base of the thoracic cavity, and when it contracts, it flattens, creating a vacuum that allows air to flow into the lungs.
-
Intercostal muscles: These muscles are located between the ribs and assist in the process of breathing. The external intercostal muscles help expand the chest when inhaling, while the internal intercostal muscles are involved in forced exhalation by helping to pull the ribs downward and inward.
Together, these muscles work in coordination to facilitate the breathing process.
