The left lung ——-has secondary bronchi since it has ———-lobes; the right lung has ———-lobes and ——-secondary bronchi.

2,2,3,3

Which arteries supply blood to the walls of the bronchi?

Bronchial arteries

Contraction of the smooth muscle surrounding the bronchioles results in

Bronchoconstriction

The figure shows the right and left lungs separated into 8-10 different colored ———- segment

Bronchopulmonary

Because the ————help produce turbulence, in the inhaled air, in the nasal cavity, they are called the "turbinate" bones.

Conchae

Failure of the left ventricle may cause accumulation of fluid in the pleural cavity. This condition is known as pleural

Effusion

The ——— of the lung is where the bronchi, pulmonary vessels, lymph vessels and nerves pass through.

Hilum

Incomplete rings of ————-cartilage support the wall of the primary bronchi to ensure that they remain open.

Hyaline

Which Is always higher, Intrapulmonary pressure or intrapleural pressure?

Intrapulmonary pressure

An inflammation of the larynx is

Laryngitis

In the respiratory system, sympathetic fibers Innervate the lungs, bronchlal tree, the trachea, and the

Larynx

In the respiratory system, sympathetic fibers innervate the lungs, bronchial tree, the trachea, and the

Larynx

The——-is also called the voice box.

Larynx

Which is NOT part of the upper respiratory system?

Larynx

The secondary bronchl that branch off the primary bronchi are also called ————bronchl.

Loba

The secondary bronchi that branch off the primary bronchi are also ———-called bronchl.

Lobar

Excess fluld Is removed from the lungs via ______vessels.

Lymph

Both the growth of the thyroid cartilage and the longer and thicker vocal folds in mature ————-help to explain why males typically have deeper voices than

Males, females

The auditory tubes connect the nasopharynx to the ———ear.

Middle

The nose is supported superiorly by paired _____________ that form the bridge of the nose.

Nasal bones

The ————- ————divides the nasal cavity into left and right portions.

Nasal septum

The ______fissure separates the superior and Inferlor lobes of the left lung.

Oblique

The ———-receptors are stimulated when airborne molecules are inhaled and dissolved in the mucus covering the ———epithelium.

Olfactory , olfactory

The ———is a common respiratory and digestive pathway through which both air and swallowed food and drink pass.

Oropharynx

the box. A condition that occurs when free alr gets Into the pleural cavity Is called a

Pneumothorax

XMo A lubricating fluld found In the pleural cavity is _______fluid.

Serous

If no other forces were acting on the lungs, they would collapse. What is the reason for this?

The elastic tissue of the lung

The lungs remain inflated despite their tendency to collapse. What is the reason for this?

The negative intrapleural pressure relative to intrapulmonary pressure.

What prevents small bronchioles from collapsing?

Their small diameter

The ————is also known as the "windpipe".

Trachea

True or false: Smoking leaves deposits in the lung tissues altering the normal color.

True

The closing of the epiglottis over the larynx along with the simultaneous contraction of abdominal muscles, known as the ——— maneuver, results in an increase in abdominal pressure.

Valsalva

A collapsed lung remains down until——— has been removed from the pleural space.

air

Normally, only_____passes through the nasopharynx.

air

The wide———- of the lung rests upon the diaphragm.

base

The main function of the sympathetic innervation on the lungs is

bronchodilation

The left lung, being smaller than the right, has an anterior indentation called the

cardiac notch

Alveolar pores provide

collateral ventilation

The bony projections along the lateral wall of the nasal cavity are called——-and the air passages that lie between them are called nasal meatuses.

conchae

Between the superior and middle ———-is the ———-meatus.

conchae, superior

and The laryngopharynx extends inferiorly from the hyoid bone and is continuous with the larynx

esophagus

Letter A is pointing to the ———sinus and letter B is pointing to the ——-sinus.

frontal, sphenoid

The conchae are located along the ———walls of the nasal cavity.

lateral

Each bronchopulmonary segment is divided into many

lobules

The trachea is part of the _________ respiratory system.

lower

The trachea descends through the neck Into the ———-from the ————to the main bronchi.

mediastinum; larynx

Gas "conditioning" is facilitated by the twisted pathways through the ———as this means the air gets to stay longer.

nasal cavity

The ——-tonsils are also called adenoids.

pharyngeal

The ————tonsil is being indicated in the figure with the letter X.

pharyngeal

Aspirated foreign objects are more likely to become lodged in the———- primary bronchus.

right

The ———lung is divided into superior, middle and inferior lobes.

right

type I

Near the vestibule of the nose are coarse hairs called

vibrissae.
