The Left Lung has a ________ Lobe and ________ Lobe, separated by the ________ ________.
Superior
Inferior
Oblique Fissure
What are the lobes of the Right Lung?
Superior Lobe
Middle Lobe
Inferior Lobe
What fissure separates the Superior and Middle Lobes from the Inferior Lobe of the Right Lung?
Oblique Fissure
What fissure separates the Superior and Middle Lobes of the Right Lung?
Horizontal Fissure
What is the superior most aspect of the Lungs called?
Apex
What are the 3 surfaces on each Lung?
Costal Surface (opposes the rib cage) Mediastinal Surface (opposes the Mediastinum) Diaphragmatic Surface (opposes the Diaphragm)
This is the portion of the Lung where things are moving in and out of it.
Hilum
***Remember, to help orient yourself on which lung you’re looking at the Hilum ALWAYS points medially!
What are the components of the Hilum?
Pulmonary A.
Pulmonary V.
Main Bronchi
Pulmonary L.
This component of the Hilum is typically more superior and has thicker walls.
Pulmonary A.
This component of the Hilum is typically more anteroinferior and has thinner walls.
Pulmonary V.
This component of the Hilum is typically more posteroinferior and is the thickest-walled structure. It also contains cartilage in the its walls.
Main Bronchi
This component of the Hilum consists of hangin pleura from the root of the lung.
Pulmonary L.
What grooves lie on the Mediastinal Surface of the Right Lung?
Cardiac Impression Groove for Azygous V. Groove for Esophagus Groove for Superior Vena Cava Groove for Inferior Vena Cava Groove for 1st Rib Groove for Brachiocephalic V.
What grooves lie on the Mediastinal Surface of the Left Lung?
Cardiac Impression (larger than Right Lung) Groove for Aortic Arch Groove for Descending Aorta Groove for 1st Rib Groove for Subclavian A.
What are the borders of the lungs?
Anterior Border
Posterior Border
Inferior Border
What is on the anterior border of the Left Lung?
Cardiac Notch – indentation on anteroinferior portion of Superior Lobe
Lingula – thin process of the Superior Lobe (lies inferior)
What recesses does the inferior border of the lungs project into?
Costodiaphragmatic Recess
Costomediastinal Recess
***These are spaces where fluids can fill
Lung cancer can derive from actual lung tissue, or from the _______.
