Test Four Respiratory Flashcards
Function of type one pneumocytes
Responsible for gas exchange, simple squamous
What does bronchioles depend on to sustain wall diameter
Smooth muscle e
Dendritic brush cells are
Sensory cells
What is located in trachea
Hyaline cartilage, smooth muscle (trachealis), fibroelastic cartilage at end of caritlage, mucous glands
Epi of bronchi
Respiratory epi
The interstium next to alveoli contains
Capillaries, elastic and reticular fibers, fibroblast and macrophages
Epi of trachea
Respiratory
Immature brush cells are
Parent cells of goblet cells
Epi of alveolar duct
Simple squamous with smooth muscle
What is found in bronchi
Mucus glands and lymphoid nodules
What is located in the epi of the bronchi
Isolated hyaline cartilage plates that decrease as move into lung
What significant thing in respiratory bronchiole
Saccular aveoli outpockets lined with simple squamous for gas exchange
What cells are present in alveolar duct
Type two pneumocytes
What supports the alveolar duct
Elastic and collagen fibers
Small granular cells are
APUD and responsible for control of respiratory system
The respiratory system is made up of
Lungs and a system of tubes linking the sites of gas exchange to external environment
The respiratory epithelium is
Pseudostratified columnar with cilia
Epi of respiratory bronchioles
Ciliated cuboidal with clara cells, smooth muscle and elastic tissue
Describe epi of bronchiole
Upper portion contains respiratory epi with mucous glands and lower portion going to have simple cuboidal
The respiratory zone has what
Increased surface area for gas exchange
Function of ciliated columnar cells
Protection of respiratory system and help move mucous form deep to oral cavity
Trachea is part of what system
Conducting
What are Clara cells
Cuboidal shaped, no cilia, apical granules
Respiratory bronchioles are part of what system
Respiratory
As the tranchea keeps dividing, what happens
Increases surface area for gas exchange
Respiratory means
Gas exchange
What replaces hyaline cartilage plate in bronchi
Smooth muscle
Alveoli contain
Endothelium of capillary, type 1 and 2 pneumocytes and dust cells
Conducting means
Conduction of air only
Function of type 2 pneumocytes
Cuboidal, primary source of surfactant
Respiratory system divided into what three systems
Conducting, transitional and respiratory
What are the three parts of the respiratory system
Conducting, transitional, respiratory
Clara cells secrete
Surfactant
What are dust cells
Alveolar macrophages
Transitional means
Conduction of air and gas exchange
Bronchiole is part of what system
Conducting system
What are the cells in the respiratory epithelium
Ciliated columnar, goblet, immature brush cells, dendritic brush cells, basal cells and small granular cells
What type of cells are present in bronchioles
Clara cells
Basal cells are
Parent cells to all cells in epi except goblet
