The respiratory system may be a system consisting of specific organs and structures used for gas exchange in animals and plants.

What is the process of respiration?

  • We have a pair of external nostrils opening out above the upper lips. It results in a nasal chamber through the nasal passage.
  • The nasal chamber opens into the pharynx, some of which are the common passage for food and air.
  • The pharynx opens through the larynx region into the trachea.
  • Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the extent of the 5th thoracic vertebra into a right and left primary bronchi.
  • Each terminal bronchiole gives rise to a variety of very thin, irregular-walled, and vascularized bag-like structures called alveoli.
  • The branching network of bronchi, bronchioles, and alveoli comprise the lung.

Thus, we can conclude that the correct option is (e).

The oral cavity to the nasopharynx to the trachea to the right and left main bronchi.
