dissection lungs Flashcards
where does the mediastinum exist
thoracic inlet to diaphragm
contains heart, trachea, oesophagus, thoracic duct ,vagus/phernic nerve, sympathetic chain, lymph nodes
lungs difference
right - 3 lobes hriziontal fisse -4th oblique left -2 lobes oblique -6th lobes receive own segmental bronchus
hilum
site of entry to lung for bronchial artery pulomayr artery/vein nerves lympatics
sruuoudned by plural health where pleura becomes continous
where do the apex of the lungs expand to
3cm above clavical
pleura and fluid
visceral inner
pariteal outer
pleural fluid - adherence between layers, attatchement to thorax wall
what happens if pleural cavity fills with air (name )
pnemothorax
lung collapse
- chest tube for evacuation
blood supply to the lungs
pulmonary arteries from the heart (1)
pulmonary veins back to heart (2)
bronchial arteries (branches of decending thoracic aorta) supply pulmonary tissues, bronchi, bronchioles CT of lungs and visceral pleura
bronchial tree right and left
enter at hilium
right - more vertical, shorter, fatter
left - more angled
lumbar bronchi, segmental bronchi, terminal bronchi
counting ribs from
second rib
sternal angle
level of 4th vertebrae
what is the surface marking for the oblique fissure
6th rib
inferior border of the lung in a superioposterior direction
surface markings horzontal fissure
4th rib horizontal frem sterum to meet oblique fissure
lower border of the lungs
right 6th rib mid claviclualr 8th mid aux 10th rib VC left same but at 4th coastal cartilage border runs left then to mid clav 6th
listening for upper lobe sounds
anterior 2nd IC mid clav space
posterior C7-T3
sounds of middle lobe right
anterior 4th mid clav
lower lobes sounds
bilaterally anterior 6th IC mid aux line
posterior T3-T10
