Teriary (segmental) bronchi
Are 10 per lung; each penetrates a bronchopulmonary segment of the lung
Terminal bronchioles
Teriary bronchi branch to form?
trachea to terminal bronchioles
The "brachial tree" runs from?
Decrease
Cartilage plates
Cartilage rings ___________ in size to become __________
(structural change in bronchioles)
Smooth
______ muscles replace cartilage
(structural change in brinchioles)
Simple cuboital
Pseudostratified columnar cells change to ____________ (stuctural change in bronchioles)
True
True or False; Bronchioles have smooth muscle and no cartilage
Lobules; each one recieves a terminal bronchiole
Bronchopulmonary segments are composed of ___________
Lobules
Bronchiopulmonary segments; note- terminal and respiratory bronchioles and air sacs belong to a lobule
Characteristics of lobule
Elastic connecive tissue
Lymphatic vessel
Arteriole
Venule
Branch a terminal bronchiole; divide to form respiratory bronchioles
Respiratory bronchioles
Derived from terminal bronchioles
Alveolar ducts (atria)
Respiratory bronchioles divide to form?
Alveolus
A single cup-like strucutre; has an elastic basement membrane
Alveolar sac
A number of aveoli (2 or more) that share a common opening
Alveolar wall composed of: -
Type I alveolar cells (squamous pulminary epithelial)

-Type II Alveolar (septal)cells

-Alveolar macrophages
Teriary (segmental) bronchi
Are 10 per lung; each penetrates a bronchopulmonary segment of the lung

Cartilage rings ___________ in size to become __________
(structural change in bronchioles) Decrease
Cartilage plates
Smooth
______ muscles replace cartilage
(structural change in brinchioles)
Simple cuboital
Pseudostratified columnar cells change to ____________ (stuctural change in bronchioles)
True
True or False; Bronchioles have smooth muscle and no cartilage
Lobules; each one recieves a terminal bronchiole
Bronchopulmonary segments are composed of ___________
Type I alveolar cells
Most gaseous exchange occurs here
Type II alveolar cells
Secretes alveolar fluid, moistens cells, also secretes surfaactus
Surfactant
Reduces surface tention of alvealar fluid and reduces change of alveolar collapse
Alveolar macrophages (dust cells)
are wandering phaocytes
Alveolar-Cappilary (respiratory) membrane -
Alveolar wall
-Basement membrane of alveolar wall
-Basement membrane of capillary wall
-Endothelium of cavity wall
