The Respiratory System Flashcards
what are the major functions of the respiratory system
Exchange gases between the atmosphere and the blood, Homeostatic regulation of body pH
Protection from inhaled pathogens and irritating substances, vocalisation, source of water loss and heat loss
how does the anatomical structure of the respiratory system support the major functions
describe the vocal folds in voice production
Mucous membrane of the larynx form two types of pairs of folds
- superior pair (Vestibular Folds) - false vocal folds
- Inferior Pair (vocal folds) - true vocal folds, elastic ligaments
define oropharynx
The part of the pharynx that lies between the soft palate and the hyoid bone
define cricoid cartilage
The ring-shaped cartilage of the larynx
define vestibular folds
False vocal cords
define pleural fluid
The fluid that is found between the layers of the pleura, the membranes of which the cavity surround the lungs
what are the two different structure parts of the resp system
The upper respiratory system
and the lower respiratory system
What are the different components of the upper respiratory tract
Mouth, nasal cavity, pharynx, larynx
What are the different components of the lower resp system
trachea, 2 primary bronchi, their branches and lungs
What are the two different functionality components of the resp system
- the conducting zone (the pipes)
- respiratory zone (the exchange area)
Each lung is enclosed and protected by double layered serous pleural membrane which membrane lines the thoracic cavity? Parietal or Visceral?
Parietal Pleura
Each lung is enclosed and protected by a double-layered serous pleural membrane which membrane cover the lungs? Parietal or Visceral?
Visceral
What is surfactant ?
A mixture of proteins and phospholipids the coat the inside of the alveoli.
