tongue-like flap covering heart

Main Bronchus

Lobar Bronchus

Tertiary Bronchus

Right Main Bronchus

This bronchus is wider and more vertical than other side

Diaphragm

bases of the lungs sit on the ____

Pleural Cavity

Parietal Pleura

Visceral Pleura

Cervical Pleura

Mediastinal Pleura

Costal Pleura

Diaphragmatic Pleura

Pleural Fluid

Visceral and Parietal Pleura are in direct contact, but separated by

atelectasis

Partial or complete collapse of a lung or a lobe of a lung

Closed pneumothorax

Air enters the pleural cavity via a hole in the lung itself

Open pneumothorax

Air enters the pleural cavity via a hole in the thoracic wall but is able to escape whenever the patient exhales

Tension pneumothorax

Air enters the pleural cavity via a hole in the thoracic wall but is unable to escape due to a one-way valve in the wall

Superior Thoracic Aperture

Inferior Thoracic Aperture

Costal Margin

decressed

During quiet inspiration, pressure inside is _____ compared to outside pressure

increased

During quiet expiration, pressure inside is _____ compared to outside pressure

Anterior Rami of C3-C5 Spinal Nerves

Phrenic nerves arise from

paralysis of the diaphragm on the ipsilateral side

High cervical spinal cord injuries can result in

drawn superiorly toward the decreased pressure zone on that side
