Breath mechanics

Breathing mechanics are fundamental to both mental and physical states. The primary components involved in breathing include the nose, mouth, larynx, lungs, alveoli, and the diaphragm and intercostal muscles.

• Nose and Mouth: These are the main paths through which air enters the system.
• Larynx: It remains rigid to prevent collapse while breathing.
• Lungs and Alveoli: The lungs act like bellows, inflating and deflating to facilitate air movement. Inside the lungs, the alveoli increase surface area for gas exchange.
• Diaphragm and Intercostal Muscles: These muscles help expand and contract the lungs.

Additionally, breathing through the nose can be slightly more challenging due to higher resistance, which is a normal physiological feature and can be beneficial as discussed by Andrew Huberman. He also points out that understanding and controlling these components can significantly affect our ability to regulate our body's response to various states 1 2.
