Definition
ventilation
Term
which muscles are involved in respiratory VENTILATION?
Definition
diaphragm, intercostal muscles, abdominal muscles
Term
contraction of respiratory ventilation muslces creates an increased (positive/negative) intrathoracic pressure, moving air (in/out).

conduction (movement of air)
Term
adaptations of the conducting airway.
Definition
warming of air, moistening of air, cleaning of debris, and cleaning of mucus.
Term
embryological origin of the respiratory system
Definition
endoderm. (diverticulum undergoes BRANCHING MORPHOGENESIS)
Term
layers of the respiratory lining (from lumen going outward)
Definition
epithelium (usually pseudostratified epithelium with goblet cells); lamina propria; connective tissue w/ glands and SOMETIMES CARTILAGE; smooth muscle; adventitia
Term
adventitia
Definition
outermost connective tissue layer of an organ or other structure. term used when the connective tissue IS THE OUTERMOST LAYER OF AN ORGAN!! No epithelium present, only connective tissue.
Term
epithelial layer together with the lamina propria forms the ___ ______.
Definition
mucous membrane
Term
which portion of the respiratory system is known as 'Anatomic Dead Space'
Definition
conducting system
Term
Name the sections of the conducting zone

pseudostratified ciliated columnar epithelium w/ goblet cells
Term
most of the conducting system (below the larynx) contain ___, _____, and ____ in their walls.
Definition
smooth muscle, elastic fibers, hyaline cartilage (except terminal bronchioles)
Term
Describe the breakdown of the respiratory system
Definition
respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
Term
what type of elithelial layer is on the respiratory portion of the respiratory system

what is a 'swell body'?
Definition
large thin-walled vascular venous plexuses that surround the conchae in the nasal cavity. They swell periodically on opposite sides of the nose.
