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
Divides to form several alveolar ducts
Alveolar ducts (atria)
Derived from respiratory bronchioles
Consists of:
Alveolus
Alveolar sacs
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
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)
Type I alveolar (squamous pulmonary epithelial) cells
Most gaseous exchange occurs here
Type II alveolar (septal) cells
Secretes alveolar fluid -moistens cells; also secretes surfacactant
Surfactant
Reduces surface tension of alveolar fluid and reduces chance of alveolar collapse.
Alveolar macrophages
dust cells
are wandering phagocytes
Alveolar-Capillary (respiratory) membrane
wall btwn cappilary membrane and wall of alveolar sac
-Alveolar wall
-Basment membrane of alveolar wall
-Basement membrane of capillary wall
-Endothelium of capillary wall
Respiratory center
consists of a widely dispersed group of neurons functionally divided into 3 areas within the Brain Stem:
-Medullary rhythmicity area in medulla
-Apenutsitc area in pons
-pueumontaxic are in pons
Fibroblasts
_________ are also present that produce reticular and elastic fibers.
