In which of the following parts of organisms, the process of gaseous exchange during respiration does not take place?

Options

  1. ASkin of earthworms
  2. BBronchi of humans
  3. CGills of Pila
  4. DAlveoli of humans

Correct answer

B. Bronchi of humans

Step-by-step solution

The human respiratory system is divided into a conducting zone and a respiratory zone. The conducting zone includes the external nostrils, nasal passage, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles. This part transports air to the alveoli, clears it of foreign particles, humidifies it, and brings it to body temperature. Gaseous exchange does not occur in the conducting zone. The respiratory zone consists of the alveoli and their ducts, which are the actual sites of gaseous exchange betw
