Respiratory System Flashcards
The Respiratory System is classified into two parts:
- Structural
- Functional
Structural Pulmonary System is composed of the following:
Upper Respiratory System- nose, nasal cavity, pharynx
Lower Respiratory System- trachea, larynx, bronchi, bronchioles, and lungs.
The functional Pulmonary System is composed of the following:
- Conducting Zone
- Respiratory Zone
It consists of all airways that carry air to the lungs
Conducting Zone
Site within lungs where gas exchange occurs:
Respiratory Zone
It is visible on the face and consists of supporting frameworks of bone and hyaline cartilage
External Nose
Opening that connects the nasal cavity to the pharynx
Internal Nares
Internal Nose
Nasal Cavity
Nostrils
External Nares
Divides the nose into two sides
Nasal Septum
It is covered by mucous membrane
Nasal Conchae
It is a groovelike air passageway
Nasal Meatus
A funnel shape tube is used for swallowing, speech, sound resonation, and passageway for air and food. Also, it houses the tonsils.
Pharynx
Three regions of pharynx:
- Nasopharynx- Upper
2 Oropharynx- Middle - Laryngopharynx- Lower
It is posterior to the nasal cavity and extends to the soft palate
Nasopharynx
The arch-shaped muscular partition between the nasopharynx and the oropharynx is lined with mucous membrane.
Soft Palate
Posterior to mouth
Oropharynx
It connects with both the esophagus and larynx: food and air
Laryngopharynx
V-shaped where Adam’s apple and Vocal cords strung here too and to arytenoids.
Thyroid Cartilage
It is a leaf-shaped piece that covers the airway.
Epiglottis
Inferior most portion and land mark for tracheostomy
Cricoid Carilage
It is superior to the cricoid and the most significant cartilage because it directly influences the vocal cords for speech.
Arytenoids
A wedge-shaped cartilage
Cuneiform
A horn-shaped cartilage
Corniculate
How is sound/speech being produced?
Vestibular and Vocal folds aided by laryngeal muscles
False vocal cords that are activated while holding breath.
Vestibular Folds
True vocal cords that are responsible for the main sound or speech production
Vocal Folds
The louder the sound produced, __________.
the greater the pressure of air
- Mainly made of 9 cartilages and a short connection between the pharynx and trachea.
- another term of this structure.
- Larynx
