1

Fissures of lungs

Right: transverse fissure 5th rib laterally to 4th costal cartilage anteriorly. oblique fissure from T3 to 6th rib anteriorly
Left: oblique fissure

2

Pneumothorax what

Air enters pleural cavity->collapses lungs->shift other chest structures over to fill gap->shift heart position. Every breath increases pressure of lungs and compress heart decreasing cardiac function

3

Bronchopulmonary segments

Right: upper-3 segmental bronchi, middle-2, lower-5
Left: 10/8 segments in total

4

Lung root composition

Pleural reflection surrounding (top to bottom) bonchus, artery, vein

5

Vessels articulating with lung

Right: vena cava, subclavianartery, oesophagus
Left: aorta, oesophagus, subclavian artery, brachiocephalic vein

6

Bottom of right lung indication

10th rib posteriorly 8th rib laterally

7

where pleura seperates

4th costal cartilage

8

Lymphatic drainage

All lymph nodes go upwards ipsilateral for right lung but can be contralateral for left. Lymphatics follow bronchial tree and drain in veins. Inferior bronchial lymph node, intrapulmonary lymph node

9

Innervation of lung

Parasympathetic (vagus nerve), phrenic nerve, sympathetic nerve originating T2-4
