What to Focus On

  • Simple diffusion is enough for many lower animals
  • Humans have a conducting part and an exchange part in the respiratory system
  • Larynx helps in sound production and is called the sound box

  • Inspiration and expiration occur due to pressure differences
  • Inspiration needs intra-pulmonary pressure lower than atmospheric pressure
  • Expiration occurs when intra-pulmonary pressure becomes higher than atmospheric pressure

  • TV is about 500 mL
  • IRV is about 2500 to 3000 mL
  • ERV is about 1000 to 1100 mL

Common Mistakes to Avoid

Inspiration happens when the pressure inside the lungs becomes higher than atmospheric pressure.

Expiration is an active process that needs the diaphragm to contract.

The trachea divides into bronchi at the level of the diaphragm.
