Alveoli
______ are the tiny saclike units in which gas exchange occurs
Trachea, 4-5"
The trunk of the tracheobronchial tree is the _____, or windpipe, which carries air
to the lungs. The trachea extends about ____-____", from the larynx to the left
and right mainstem bronchi
Carina, 5th
The ridgelike point at which the tracheal cartilage bifurcates is called the ______.
It is roughly the level of the ____ intercostal space
,Right, left, right
In adults, the ______ mainstem bronchus typically branches at a less acute angle
than the _____. This explains why an ET tube advanced to far almost always ends
up in the ______ mainstem bronchus, as well as aspirated materials
3, 2
The right lung has ____ lobes, the left has ____ lobes
Dead space
All airways that do not participate in gas exchange represent _____ _____
Bronchioles
Gas transfer is most efficient in the alveoli, but a significant amount is also
exchanged across the respiratory ______
,Parenchyma
Once foreign material reaches the terminal bronchioles and alveoli, parts of the
lung collectively known as the lung _______, it may never come out. Common
substances include coal dust, asbestos fibers, and contaminants in cigarette
smoke
Smooth
Bronchoconstriction occurs when the _____ muscle narrows the larger airways
Constriction
Wheezing that resolves with administration of bronchodilator medication was
probably caused by the _______ of the smooth muscle
Deeper
Wheezing not resolved by bronchodilator medications may have been caused by a
pathologic condition ______ in the tracheobronchial tree
, Pulmonary artery
Blood flows from the heart to the lungs via the _____ _____, which branches into
smaller arteries, arterioles, and finally capillaries
Bases, apices
The lung bases have more capillaries than the apices do, so more gas exchange
takes place between the lung ______ and the circulatory system than between
the ______ and the circulatory system
Bases, apices
Problems in the ______ of lungs impair ventilation more than do problems
affecting the ______
RBCs
People with chronic lung disease and chronic hypoxia often generate a surplus of
_____ over time, which makes their blood thick
