PULMO ANAPHY Flashcards
(46 cards)
– Filters & warms (humidifies)
air
– Respiratory mucosa lines the
nasal cavity is ciliated
epithelium that contains goblet
cells.
NOSE
– Common area for respiratory &
gastrointestinal system
Pharynx
– For voice/sound production
– Ensures that air will pass
through the trachea
Larynx
– Descends from the
larynx into the thorax
and is situated anterior
to the esophagus
Trachea
Other name for Trachea
Wind pipe
The 5 areas that make up the respiratory zone
Respiratory Bronchioles
Alveolar Ducts
Alveolar Sacs
Alveoli
Capillaries
cover 70% of the internal surface of each alveolus. These cells are thin and squamous, ideal for gas exchange. They share a basement membrane with pulmonary capillary endothelium, forming the air-blood barrier where gas exchange occurs.
Type 1 Pneumocytes
synthesizing cells of the alveolar surfactant, which has important properties in maintaining alveolar and airway stability. Lung surfactant can reduce the surface tension and prevent alveolar collapse and the airway walls collapse.
Type 2 Pneumocytes
two muscles responsible for relaxed inspiration
-Diaphragm
-External Intercostals
five muscles respponsible for forced inspiration
-SCM
-Upper Trapezius
-Pecs Major/Minor
-Ant/Middle/Post Scalenes
-Serratus Ant
two muscles of forced expiration
-Abdominals
-Internal Intercostals
