Question 9

Question
Although the lungs are only attached to the body at the [blank_start]hilus[blank_end], the lungs fill the volume provided in the thoracic cavity because of [blank_start]negative[blank_end] [blank_start]intrapleural[blank_end] [blank_start]pressure.[blank_end]

Question 11

Question
The purpose in the cartilaginous rings in the trachea are:
Answer
  • Maintain constant pressure and even air flow
  • allow for optimal vital lung capacity
  • prevent it from collapsing
  • allow for deglutition (swallowing)

Question 12

Question
Most of the resistance in the respiratory system is found in the intrapleural space and thus it is filled with fluid to ease this problem.
