Lung Anatomy and Histology
Goals for this activity:


View and identify key features of lung anatomy from fresh sheep lung, human cadaver and fetal
pig
Use microscope to view and identify key features in histology slides of alveoli, bronchioles,
trachea
Part I: Lung Anatomy
SHEEP PLUCK—watch demo of inflating lung by blowing into trachea
 Lobes of lung
 Trachea
 Primary bronchii
 Understand and analyze that blowing into trachea is NOT how lung really works inside body.
Observe model of balloon lungs with rubber diaphragm to appreciate how lungs really fill with air.
CADAVER AND FETAL PIG LUNG/CHEST CAVITY
 Lobes of lung
 Trachea
 Primary bronchi
 Diaphragm
 Ribs and intercostals muscles
 Abdominal muscles—rectus abdominus, external and internal obliques
 Phrenic nerve to diaphragm from cervical spinal cord
 Serous linings of chest cavity: parietal pleura, visceral pleura, mesentery covering structures of
mediastinum
 Pneumothorax
 Sucking chest wound
Part II: Histology of lung tissues
OBSERVE MICROSCOPE SLIDES OF BRONCHI, BRONCHIOLES, TRACHEA
 Hyaline cartilage
 Pseudo-stratified ciliated epithelium
 Goblet cells
 Mucous glands
 Appreciate “shag carpet” of cilia forming “mucous elevator” coating entire respiratory epithelium
OBSERVE MICROSCOPE SLIDE OF ALVEOLI
 Simple squamous epithelium
 Form of alveolar clusters
 Capillaries and small blood vessels
 Dust cells
 pneumocytes
