Knowledge Organization Template for the Lung
1.What is the definition of lung?
The
lung is a parenchymatous lobular viscus, the parenchyma of which consists of
microscopic air-filled sacs, the pulmonary alveoli.
2. What does it look like? (select various images from the available resources)
Digital
Anatomist Atlas of Thoracic Viscera
2D image of 3Dmodel without labels, with labels.
X-ray from radiology tutorial with and without
annotation,
3. What is its “canonical” shape? (e.g. 3-D shape approximation - pyramid, cylinder, cone)
Dimensional entity->Volume->Composite->Hetero-composite->Conventional
cone
Or
Dimensional entity->Volume->Faceted volume-Polyhedron->Pyramid
4. What kinds of surfaces does it have?
First predict from the canonical shape of the organ the kind of surfaces you expect the organ to have.
Anterior, posterior, lateral, medial, inferior or base
Then look at the interactive atlases or other resources and correlate anatomical reality with the idealized shape model.
Costal surface, mediastinal surface, diaphragmatic surface
5. What are its external features?
Apex, oblique fissure, horizontal fissure, anterior margin, inferior margin
6. What are its morphological parts?
Left lung
Upper lobe of left lung
Left apical bronchopulmonary segment
Left posterior bronchopulmonary segment
Left apicoposterior bronchopulmonary segment
Left anterior bronchopulmonary segment
Superior lingular bronchopulmonary segment
Lower lobe of left lung
Left superior bronchopulmonary segment
Left medial basal bronchopulmonary segment
Left anterior basal bronchopulmonary segment
Left lateral basal bronchopulmonary segment
Left posterior basal bronchopulmonary segment
Right lung
Upper lobe of right lung
Right apical bronchopulmonary segment
Right posterior bronchopulmonary segment
Right anterior bronchopulmonary segment
Middle lobe of lung
Lateral bronchopulmonary segment
Medial bronchopulmonary segment
Middle lobe branch of right bronchial artery
Lower lobe of right lung
Right superior bronchopulmonary segment
Right medial basal bronchopulmonary segment
Right anterior basal bronchopulmonary segment
Right lateral basal bronchopulmonary segment
Right posterior basal bronchopulmonary segment
Why are they named as they are?
Are some parts of the organ also shared with other organs?
Yes. Illustrate with images of Left lung, Right lung,
TB tree, then combined
7. What is the organ a part of?
Which organ system?
Respiratory system
Which body
part?
Thorax
Thoracic cavity
9.What is it connected with (to)?
Tracheobronchial tree
Pulmonary arteries
Pulmonary veins
Plural sac
Nerves
Lymphatics
Bronchial arteries
Bronchial veins
Where?
All at hilum except pleural sac
What enters it? Where?
What leaves (exits) it? Where?
What is attached to it? Where?
pleura
10. What anatomical structures are adjacent to it?
Digital Anatomist images
of Right lung and left lung hilar
11. What supplies it with blood? (This is tricky for the lungs)
bronchial arteries
12. What drains blood from it?
bronchial veins
14. What innervates it?
Pulmonary plexus
Sensory fibers – autonomic – stretch
Motor fibers – constrict bronchii, cause glands to secrete
The following questions do not need to be answered now. They lead to other areas of knowledge:
15. How does the organ come to be the way it is? [How does it develop?]
Embryology
(ATA)
16. What does it do? What do we have it for? [What are its functions?]
Function
17.
What are its component parts?
Microscopic anatomy
