Lab Practical #1

Lab 36
Respiratory Anatomy
Lab Practical #1
• 26 stations:
– 13 microscopes
– 3 fresh hearts
– 1 heart model
– 8 vessel diagrams
– 1 blood typing
• All stations have 2 questions (an A and a
B), EXCEPT the vessel diagrams
• 1 minute per station
Lab 39
• Trachea: “Cartilage- Elastic and Hyaline” slide:
mammalian trachea is on the left half of the
slide. Draw and clearly label the trachea at low
power and at one higher power. Label:
respiratory epithelium (state the type), goblet
cells, glands in the mucosa layer, cartilage
(name the type); within the cartilage, identify
chondrocytes and lacunae. Bracket and label
the lamina propria. Label any blood vessels and
RBC’s seen in your view.
Lung slides
• Lung: “Lung Human - simple squamous” Draw
and clearly label the lung. Identify the alveoli
and an alveolar duct. In addition, try to find and
label at least one bronchiole, one arteriole and
one small vein.
• Two lung tissue samples: look at side by side:
“Lung-Containing Carbon Particles” and “LungEmphysema.” Sketch and clearly label what you
see in the “Lung-Emphysema” slide. Label a
bronchiole and alveoli.
Four Drawings
• Two trachea: one low and one medium or
high power
• Normal lung
• Emphysemic lung – loss of elasticity,
increased compliance
• You don’t have to draw the carbon particle
lung but you need to look at it.
• Be able to identify the following structures
on a model: trachea, larynx, bronchi,
bronchioles, nasal cavity, nasal conchae,
pharynx, lungs.
Cow Pluck

• Turn in your drawings along with the
Review Sheet for Lab 36
