Study Notes

Respiration vs. Breathing

  • Respiration is a broader term encompassing air intake, oxygen utilization, and energy production in body cells.
  • Breathing is a mechanical process of inhaling and exhaling air, involving muscles but not necessarily energy production.

Respiratory Cycle

  • The respiratory cycle includes inspiration (breathing in), expiration (breathing out), and a short pause.
  • Normal adults typically breathe 12-18 times per minute.
  • Newborns breathe 60 times per minute.
  • An increased COâ‚‚ level in the blood triggers a faster breathing rate.

Inspiration (Inhalation)

  • Inspiration results from an increase in the thoracic cavity size.
  • This is due to the combined action of the ribs and diaphragm.
  • Ribs move upwards and outwards, and the external intercostal muscles contract. This expands the chest cavity.
  • The diaphragm, a sheet of muscle below the lungs, contracts and flattens, further expanding the chest cavity.
  • Internal intercostal muscles are relaxed during this process.
