The lungs are separated by the
Answer: mediastinum.
The mediastinum contains
Answer: the heart, the great vessels and the esophagus.
Lobes on each side of lungs
Answer: There are 3 lobes on right side and 2 lobes on left side of the lungs.
The conducting airways are referred to as the
Answer: bronchi and they are what deliver air to each section of the lung.
The diaphragm is a
Answer: dome shaped muscle that separates the abdominal and thoracic cavities
and is important for ventilation.
Texture of the lungs
Answer: they have a spongy, soft texture
The carina is where the bronchus divides between the
Answer: right and left main stem.
The carina is about level
Answer: T5, the same level as the aorta. The left bronchus has a sharper angle, due
to the placement of the heart in the chest. This explains a bit why the endotracheal
tube ends up in the right main stem bronchus during intubation so often.
Implications of the more vertical angle of the right main stem bronchus
Answer: It branches at about 20-30 degrees and is also a bit larger than the left. This
means that the right middle lobe is an easy dumping ground for bacteria, so it's the
most common site for infiltrate.
The suprasternal notch is the
Answer: soft spot just above sternum.
The manubrium is that
Answer: first part of sternum and the sternal body below that.

The notch between the manubrium and the sternal body is called the
Answer: "angle of Louis"
The right lung has the
Answer: upper, middle and lower lungs.
Each lobe of the lungs are separate by
Answer: a fissure.
There is an oblique and horizonal fissure on the
Answer: right side of the lungs.
On the left side you have an
Answer: upper lobe and lower lobe separated by another oblique fissure.
The left lung does have a middle lobe or sorts, its known as the
Answer: lingula.
The left upper lobe is very large but you can see how
Answer: its comparable to the upper and middle lobes of the right side.
The main difference is the lingula is not separated from
Answer: the upper lobe by a fissure.
To properly auscultate the middle (lingula) and upper lobes, you have to listen
Answer: on the anterior chest
Hila
Answer: "Root" of lungs, the medial aspect of the lungs
Upper airways
Answer: the nose and oropharynx, They provide passage for the movement of air
into the pulmonary system
The upper airways are lined with
Answer: a ciliated mucosa that will warm and humidify air as we breathe it in, it also
helps remove foreign debris (Mouth breathing does not have this same effect)
The nasal mucosa has a rich
Answer: vascular supply
, Inquire through: | Professional | Confidential Support
The nasal mucosa can become chronically inflamed in
Answer: smokers. This actually may be correlated with the development of COPD
In the larynx there is a layering of
Answer: cartilage, ligaments and the internal laryngeal muscles that are important
to the function
The cartilages of the larynx prevents collapse of
Answer: the larynx during inspiration and swallowing.
The internal and external laryngeal muscles are both essential for
Answer: swallowing, respiration and vocalization
The larynx connects
Answer: the upper and lower airways
The trachea starts the
Answer: lower airways.
the trachea connects the
Answer: larynx to the bronchi divides at carina.
the carina is a very sensitive area and when its irritated it often causes
Answer: coughing and narrowing
The bronchial walls have an (layers)
Answer: epithelial lining, smooth muscle layer and a connective tissue layer.
The epithelium contains _____ cells
Answer: goblet cells that produce mucus which catches foreign invaders.
Goblet cells are_____ cells that
Answer: epithelial cells that help protect lung tissue from the environment by
stopping foreign particles and regulating ion and water transport.
If you were to take a cross section of each successive branch of the bronchi, it gets
more and more
Answer: narrow. This decreases the velocity of airflow into the gas exchange portion
of the lung.
As the airways get smaller, they contain less
Answer: cartilage and submucosal glands.
