, What is the trachea made up of? - ANSW-16 - 20 C-shaped cartilaginous rings that keep it from
collapsing on inspiration

cm (4.5") in length
What does the trachea extend from? - ANSW-C6 to T4/T5 where it bifurcates into the right and left
primary bronchi
What is the carina? - ANSW-a prominent ridge of cartilage at the lowest point of the trachea at the
bifurcation
What is a common reference point used in cross sectional anatomy, CT, and MRI? - ANSW-the carina
What is the shape and size of the right primary bronchi? - ANSW-it's wider and more vertical than the
left, approx. 2.5 cm in length & 1.3 cm in diameter, 25° from vertical, & divides into three secondary
bronchi
Where is a common place for foreign bodies (FB) to lodge? - ANSW-the right primary bronchi
What is the shape and size of the left primary bronchi? - ANSW-Longer and narrower than right, approx.
5 cm in length & 1.1 cm in diameter, 37° from vertical, & divides into two secondary bronchi
What are tertiary bronchi? - ANSW-Bronchioles & Terminal bronchioles
What are alveoli? - ANSW-the working part of the respiratory system & where the gas exchange takes
place
What is the major lung anatomy seen in chest x-rays? - ANSW-hilum, apex/apices, base, costophrenic
angles, & cardiophrenic angles
What is the hilum? - ANSW-A wedge shaped area where bronchi, blood vessels, lymph vessels, & nerves
enter and leave the lungs
Where is the hilum located? - ANSW-Lies central & medial in the lung
What is the apex (apices)? - ANSW-the rounded area located above the clavicles
What is the base of the lungs? - ANSW-the bottom of the lungs that lay above the diaphragm
Why is the right base normally higher than the left base? - ANSW-the liver
What are the costophrenic angles? - ANSW-The angle of lung where the ribs meet the diaphragm
costo- - ANSW-ribs
-phrenic - ANSW-diaphragm
What are the cardiophrenic angles? - ANSW-The angle of lung where the mediastinum meets the
diaphragm
How many lobes does the right lung have? - ANSW-3
What are the lobes of the right lung? - ANSW-Upper/superior lobe, middle lobe, & lower/inferior lobe
How many deep fissures does the right lung have? - ANSW-2
How many lobes does the left lung have? - ANSW-2
What are the lobes of the left lung? - ANSW-Upper/superior lobe & lower/inferior lobe
How many deep fissures does the left lung have? - ANSW-1
What is the mediastinum? - ANSW-Medial portion of thoracic cavity between lungs
What are the main structures in the mediastinum? - ANSW-Trachea, esophagus, thymus gland, heart and
great vessels
