Respiratory System - Module 15 Flashcards
Respiratory System
3 Principal regions of Respiratory System
- Conducting Portion
- Respiratory Portion
- Structures of Ventilating Mechanism
What region of respiratory system is a system of ducts that conducts air to alveoli in lungs.
Conducting Portion
What comprises the Conducting portion of respiratory tract
Nasal Cavity, Nasopharynx, Larynx, Trachea, Bronchi, Bronchioles, Terminal Bronchioles
What comprises the Respiratory Portion of Respiratory tract
Respiratory bronchioles, Alveolar ducts, Alveolar sacs, Alveoli
What cartilage is found in the Larynx
Hyaline Cartilage
Changes in epithelium from Nasal Cavity to Alveoli of Lungs
Pseudostratified Columnar - Simple Columnar - Simple Cuboidal - Simple Squamous
What is the part of the throat behind nasal passages
Nasopharynx
What structure connects the ear by two openings on side of Nasopharynx
Eustachian Tubes
Layers of Nasopharynx
Mucosa, Submucosa, Adventitia
Two main types of Epithelium in Nasopharynx
Squamous Epithelium and Respiratory Epithelium
What structure keeps the Larynx open
Epiglottis
Epithelium of Epiglottis and Vocal Folds
Nonkeratinized Stratified Squamous Epithelium
Lining of Larynx
Pseudostratified Ciliated Columnar Epithelium with Goblet Cells
Known as the Voice box organ
Larynx
What organ has around 20 C-shaped hyaline cartilages
Trachea
Segments of Intrapulmonary Bronchi
Primary Bronchi, Secondary Bronchi, Tertiary Bronchi
Primary Bronchi
Lobar Bronchi
Secondary Bronchi
Segmental Bronchi
Tertiary Bronchi
Interlobular Bronchi
Lining Epithelium of Intrapulmonary Bronchi
Pseudostratified Ciliated Columnar Epithelium w/ Goblet Cells
Larger Bronchioles has ____________________ epithelium, while smaller bronchioles have ____________________
Larger Bronchioles - Simple Columnar
Small Bronchioles - Tall Cuboidal
True or False, bronchioles contains goblet cells
False, Goblet cells disappear as it transitions from Bronchi to bronchioles
Long Air passages of Alveoli
Alveolar ducts
Round Air spaces surrounded by clusters of Alveoli
Alveolar Sacs
