Lungs Flashcards
Describe the location of the lungs.
Located within the thorax, extending from their apex which is just above the first rib, level with T1. To the diaphragm level with T12 during inspiration.
What is the midclavicular line?
A parallel line passing through the mid point of the clavicle (collar bone)
Where do both lungs cross the midclavicular line?
Level with the 7th rib.
Where does the pleura cross the midclavicular line?
Level with the 9th rib.
What is the diaphragm?
A muscular dome that separates the thorax from the abdomen.
What is the level of the diaphragm at rest and where is it inferiorly attached to the body wall?
The highest point is T9 and it’s inferiorly attached to the body wall at T12
What is the pleura?
A double layer of connective tissue that envelops the organs of the thorax, it ensures the volume of gas between its layers remains constant and allows the lungs to expand with the rib cage.
