Thorax

How many lobes does the right lung have?

• Six

• Two

• Three

• One

How many lobes does the left lung have?

• Six

• Two

• Three

• One

Which of the following structures is the chief respiratory unit for gas exchange?

• Acinus

• Alveoli

• Terminal bronchioles

• Pulmonary arteries

They are called the “floating ribs”, because they have no anterior attachments

• 8th, 9th, and 10th ribs

• 11th and 12th ribs

• 10th and 11^th ribs

• 8^th and 9^th ribs

The first seven ribs articulate with:

• Cartilages

• Sternum

• They do not have anterior attachment

• Clavicle

The inferior tip of the scapula is at the level of the:

• 12^th rib

• 7^th rib

• 9^th rib

• 10^th rib

The midaxillary line drops from:

• The apex of the axilla

• The muscle masses that border the axilla

• The anterior axillary fold

• The posterior axillary fold

The visceral pleura covers:

• The inner surface of the lungs

• The pleural cavity along the inner rib cage

• The outer surface of the lungs

• Upper surface of the diaphragm

Select the correct description for hilum surface:

• Superior part of the upper lobe that extends into the root of the neck (above the clavicles)

• Area located on the medial aspect through which structures enter and leave the lung

• Anterior, lateral, and posterior aspects of the lung in contact with the costal elements of the internal thoracic cage

• Inferior part of the lung in contact with the underlying diaphragm

Structures that conforms the airway:

 

• Nasopharynx, laryngopharynx, trachea, and bronchi

• Oropharynx, laryngopharynx, trachea, and bronchioles

• Nasopharynx, oropharynx, laryngopharynx, trachea, bronchi, and bronchioles

• Oropharynx, laryngopharynx, trachea, and bronchi
