They have larger diameter than most capillaries
They have lower pressure than most capillaries
They are somatic, continuous capillaries
They exhibit tight junctions between the neighboring endothelial cells.
They lack a basal lamina
Neurons that are replaced throughout life
Receptors for taste
Trachealis muscle contracts during inhalation
Diaphragm contracts during exhalation
Smooth muscle and cartilage disappear from the airways at the same point.
As one moves from the beginning to the end of the brochiolar tree, Goblet cells disappear before ciliated cells disappear
Hyaline cartilage is found only in the larynx and trachea
Ciliated epithelial cells
Type I pneumocytes
Both contain goblet cells
Both are pseudostratified epithelia
Both contain bipolar sensory neurons
Both contain cells with motile cilia
Both contain Clara cells
Type I pneumocytes
Type II pneumocytes
Contain organelles called lamellar bodies
Phagocytize particulates reaching the alveoli
Form tight junctions with Type I pneumocytes
Divide to produce both Type I and Type II cells
Absorption of oxygen into blood
Sampling odors in air
Layer of surfactant
An endothelial cell
A Type I pneumocyte
One or more smooth muscle cells
The plasma membrane of the erythrocyte
Both the filtration barrier and the gas diffusion barrier contain two epithelial layers.
Glomerular capillaries are fenetrated capillaries while alveolar capillaries are continuous capillaries.
Alveolar capillaries have a smaller diameter and a higher hydrostatic pressure than glomerular capillaries
Both the filtration barrier and the gas diffusion barrier include at least one basement membrane.
Type I pneumocytes in the alveolus are connected by tight (sealing) junctions while the glomerular podocytes are not.
Bronchioles lack hyaline cartilage
Elastic fibers are absent from alveoli
Bronchioles have a ciliated simple cuboidal epithelium
All extrapulmonary airways have C-shaped cartilage rings
Smooth msucle is found in alveolar ducts
Smooth muscle; elastic fibers
Elastic fibers; smooth muscle
Cartilage; elastic fibers
Collagen; elastic fibers
Type I pneumocyte (Type I alveolar cell)
Type II pneumocyte (Type II alveolar cell)
