8. Respiratory System Flashcards
What specific cell produces mucous in the respiratory tract?
Goblet cell
What motile feature of the cells of the respiratory tract help move mucous?
Cilia
How many different cells are in comprise olfactory epithelium?
Three
What is the last part of the conducting portion of the respiratory system?
Terminal bronchiole
What cell type produces surfactant in the alveolus?
Type II pneumocyte
What is another name for macrophages found in the lung?
Dust cell
What type of cell secretes hormones in the respiratory tract?
Neuroendocrine cell
Air normally passes over three surfaces during respiration. Two of these surfaces include: basement membrane and type I pneumocytes. What is the third surface?
Endothelium
How is the pressure within the lung is equalized?
Pores of Kohn
What is the mesothelial lining of the lung known as?
Pleura
What kind of epithelium lines the oropharynx?
Stratified squamous
What is the name of the cell in the nasal epithelium which is largely a support cell and whose apical surface has numerous microvilli?
Sustentacular cell
Respiratory bronchioles are recognizable due to the presence of what structures in their walls?
Alveoli
What is the name for the lymphoid tissue found throughout the respiratory system?
Mucosa Associated Lymphoid Tissue
A black deposit frequently found in the lungs of city dwellers is?
Carbon
A disease in which there is marked destruction of alveolar walls is?
Emphasema
What is the most common cell type in the alveolus?
Type II pneumocyte
What kind of capillary is in the alveolus?
Continuous
What is the name of the muscle that joins the cartilage that supports the tracheal wall?
Trachealis muscle
The mesothelial layer of the lung that is attached to the lung is called the?
Viseral pleura
What are Clara cell
Cells only found in bronchioles and contain surfactant
Small holes which allows for pressure equalization in the lung
Alveolar pores
Small bronchiole with alveoli in the wall
respiratory bronchiole
How to differentiate bronchus from bronchiole?
Bronchus - see cartilage
Bronchiole - no cartilage
Which portion of the respiratory system is exclusive to the inside of the lung?
Respiratory portion
Conductive is both inside/outside lung
Key to recognizing terminal vs respiratory bronchiole
Respiratory bronchiole has alveoli in wall
Will not see lung tissue in the same section as this
Primary bronchus
Where are Clara cells found
Only in bronchioles
