Flashcards in Pulmonary Anatomy Deck (96)
The inferior thoracic aperture is closed by the ________
What are the three spaces in the chest that make up the thoracic structures?
left pulmonary cavity, right pulmonary cavity, and mediastinum
In the thorax, the blood supply (aorta, vena cava), nerve supply (vagus nerve), thoracic duct and esophagus all penetrate the __________
The superior thoracic aperture has a lot of blood vessels due to vasculature to what three areas?
head, neck, upper extremities
________ results from compression of vasculature and nerve supply penetrating superior thoracic aperture
thoracic outlet syndrome
What does the independence of pulmonary cavities signify?
You can have problems on one side but still maintain respiration on the other.
What two structures are contained within the pulmonary cavities?
Lungs and pleural sacs
The space inside the pleural sac is called the _________ and is empty
The _______ is space sandwiched in between pleura on both sides
The ______ pleural lines the lung whereas the ______ lines the body wall
What is found within the pleural space?
A tiny bit of fluid that allows the lung to slide back and forth as it expands and deflates
True/False: It is necessary to have positive pressure inside the lung during inspiration
FALSE, negative pressure to draw air in passively
True/False: In COPD, airflow in is compromised
False, can get air in, but can't get it back out
The ___________ is where the parietal pleura extends further down than the inflated lung. The normal space is about 2 ribs.
What kind of nerve is the phrenic nerve?
Somatic (that's why we can control breathing!) with some autonomic fibers
The phrenic nerve is found sandwiched in between what two structures?
Parietal pleura and fibrous pericardium
Phrenic nerve comes from what vertebral levels?
C3-C5 [C3,4,5 keeps the person alive!]
Posteriorly (paravertebrally), the lungs (visceral pleura) go to above vertebral level of ____ whereas the parietal pleura go to vertebral level of ___
Anteriorly, when looking at mid-clavicular level, the lungs (visceral pleura) go to about vertebral level of ____ and the parietal pleura to ___
If looking from a mid-axillary viewpoint, the lungs (visceral pleura) go to about vertebral level of ___ and the parietal pleura to ____
True/False: The cardiac notch has pleura over it and the lung continues into it
FALSE - the lung does not continue into the cardiac notch (does have pleural however)
Why is it important that patient raises their arms for CXR?
to get scapula out of the way
If looking along parasternal line, the lungs (visceral pleural) go to vertebral level of about ___, whereas the parietal pleura go to vertebral level of _____
________ are potential spaces which can fill with blood, air and water in pathological states.
This area of the lung consists of mainly pulmonary arteries, bronchi and pulmonary veins but anything entering or leaving the lung could also be considered part of this.
The point where the arteries, bronchi, and pulmonary veins enter the lung is the ______
Describe the differences in bronchi on each side of the hilum
On the left side. the primary bronchus enters. On the right side, the secondary bronchi for upper and lower lobes enter.
Describe where the phrenic and vagus run in respect to the hilum
The phrenic runs anterior to the hilium and the vagus runs posterior
How many secondary bronchi are there?
2 on right, 3 on left
