NCCQ anatomy and physiology revision- the respiratory
system || QUESTIONS WITH COMPLETE
SOLUTIONS.
What is the process of taking oxygen from the air and transporting it to individual body cells, and
the subsequent transportation of carbon dioxide from the cells back into the air? correct answers
Respiration
What are the functions of the respiratory system? correct answers Provides the route by which
oxygen enters the body and by which carbon dioxide is excreted. This system also plays a role in
regulating body temperature
What are the major structures of the respiratory system? correct answers The nose,
pharynx ,larynx, trachea, bronchi and lungs
How is breathing accomplished? correct answers By the diaphragm and the muscles of the chest
wall
What is the trachea? correct answers A semi-rigid tube about 115 mm long and 12 mm in
diameter
What makes up the exterior surface of the trachea? correct answers Rings of cartilage embedded
in fibrous, elastic and smooth muscle tissue
What lines the surface of the trachea? Give the function of the lining. correct answers It is lined
with mucous membrane which has a special ability to trap dust particles and move them upward
toward the pharynx
What does the trachea divide into at its lower end? correct answers The right and left bronchi
What do the right and left bronchi do? correct answers They conduct inspired air into the right
and left lungs.
Numerous branches stem from both main bronchi, why is this? correct answers So that air
reaches all segments of the lungs
What is a bronchiole? correct answers The smallest branch of the bronchial tree
What structures are composed of bronchial tubes, tiny air sacs called alveoli, blood and lymph
vessels, and nerves supported by connective, elastic and muscle tissue? correct answers The
lungs
How many lobes (sections) make up the right and left lung? correct answers The right lung has
three lobes (sections) and the left lung has two
