Respiration Flashcards
Functions of Respiration
- Exchange Gases
- Moves air into and out of respiratory pathways
- Protects respiratory system from dehydration
- Produce sounds
- Detects olfactory stimuli
- Regulates blood pH
4 Parts of respiration
- Pulmonary ventilation
- External Respiration
- Internal Respiration
- Transportation of Gases
Pulmonary Ventilation
Inspiration & Expiration
External Respiration
Gas Exchange in lungs
Internal Respiration
Gas Exchange in Tissues
Transportation of Gases
Movement of gases through circulatory system to tissues and back to the lungs
Divisions of the Respiratory System
Upper + Lower Respiratory Tracts
Boundries of the
Upper Respiratory Tract
External Nares to Larynx
Boundries of the
Lower Respiratoy Tract
Larynx to Alveoli
External Nares
Nostrils
Nose
External Structure on face
Houses nostrils and anterior nasal cavity
The Three Conchae
Superior, Middle, and Inferior
4 Paranasal Sinuses
Maxillary, Frontal, Sphenoidal, and Ethmoidal sinus
3 Regions of the
Pharynx
Nasopharnx, Oropharynx, Laryngopharynx
Nasopharynx
- Superior to soft palate
- Extends to tip of uvula
- contains opening of eustachian tube
- contains pharyngeal tonsils
Oropharynx
- Extends from tip of uvula to epiglottis
- contains palatine tonsils and lingual tonsils
Laryngopharynx
- Extends from tip of epiglottis to larynx
9 cartilages of the Larynx
Thyroid Cartilage, Cricoid Cartilage, Epiglottis, Cuneiform, Arytenoid, and Corniculate
