RUSVM Microanatomy Block 3 Questions and Answers Fully Solved
How can the respiratory system be divided? - Answers Conductive system, trasnsitional system, Gas
exchange.
What is the conductive system composed of? - Answers nasal cavity, pharynx, larynx, trachea, bronchi
What is the transitional system composed of? - Answers respiratory bronchioles
What is the gas exchange system composed of? - Answers respiratory bronchioles and alveoli
What does the conducting system do? - Answers Brings air to the respiratory portion. Cleanses,
moistens, and warms incoming air. Hair and secretions in the nasal cavity trap particulate matter.
What is the transitional system? - Answers A transition zone between the conducting (ciliated) and the
gas exchange (alveolar system) areas of the respiratory tree.
What does the transitional system consist of exclusively? - Answers Club cells, non ciliated secretory
cells, only a few ciliated cells.
What do healthy bronchioles not have? - Answers Goblet cells
What is the exchange system? - Answers It is composed of Alveoli, which are lined by epithelial type 1
(membranous) and the 2 pneuomonocytes (also known as pneumocytes)
What are the defense mechanisms of the respiratory system - Answers Non specific (non immune
mediated)
Specific (immune-mediated)
What is the respiratory portion of the nasal cavity lined by? - Answers Pseudostratified columnar
epithelium with goblet cells
What does the lamina propria contain? - Answers Tubule-alveolar glands that are mainly serous with
lesser numbers of mucous and mixed glands
What supports the lamina propria - Answers submucosa
What are the 3 regions of of each half of the nasal cavity? - Answers 1. Vestibular region
2. Respiratory region
C. Olfactory region
What is the vestibular region of the nasal cavity lined with? - Answers Stratified squamous keratinized
epithelium
