Respiratory-Anatomy Flashcards
What is included in the conducting zone of the lungs?
Large airways including the nose, pharynx, larynx, the trachea and bronchi and
small airways including bronchioles that divide into terminal bronchioles
What is the purpose of the conducting zone?
It serves to warm, humidify, and filter air but does not participate in gas exchange and thus is considered “anatomic dead space”
Cartilage and goblet cells cells to the end of _________
bronchi
Describe the epithelium of the conducting zone
It consists of pseudostratified ciliated columnar cells from the bronchi all the way to the beginning of terminal bronchi, where it transitions to cudboidal cells
What does the respiratory zone consist of?
from the respiratpry bronchioles, to alveolar ducts, and alveoli
Where does smooth muscle end in the lung?
the end of the terminal bronchioles
Cilia terminate in the _____
respiratory bronchioles. I.e. none in the alveolar sacs
What are the lobes of the right lung? Left?
The right lung has 3 lobes and the left has 2 lobes and the lingula (homolog of the right middle lobe)
Which lung is common for aspiration of a foreign body? Why?
The right lung because its anatomy is more vertical than the left
Describe the relationship of the pulmonary artery to the bronchus at each lung hilum
RALS
Right Anterior
Left Superior
Where do the aorta, esophagus, and IVC puncture the diaphragm?
I (IVE) ate (8) ten (10) eggs at (aorta) 12
What else besides the esophagus punctures the diaphragm at T10?
vagus nerve
What else besides the aorta punctures the diaphragm at T12?
the thoracic duct (white) and the azygos vein (blue)
At T-1-2, its the red, white, and blue
What innervates the diaphragm?
C3, C4, C5 from the phrenic nerve
Pain from the diaphragm (e..g air, blood, or pus in the periteonal cavity) can be referred where?
the should via C5 or the trapezius ridge via (C3, C4)
