What determines where particles will be deposited in the respiratory tract?

  1. The pH level of the particles

  2. The aerodynamic diameter of the particles

  3. The temperature of the air being inhaled

  4. The velocity of air intake

The correct answer is: The aerodynamic diameter of the particles

Particles are deposited in the respiratory tract based on their aerodynamic diameter, which is a measure of their size and shape. The pH level of particles, while important for chemical reactions and biological processes, does not play a significant role in determining where they will be deposited. The temperature of the air being inhaled and the velocity of air intake may impact the overall movement and distribution of particles, but they do not directly determine where particles will be deposited. It is the aerodynamic diameter that ultimately determines how particles interact with the respiratory tract and where they will settle.
