Ch.23 Respiratory System Flashcards
Structures of Respiratory System(4-6)⭐️
Nasal Cavity
Pharynx & Larynx
What is the glottis?⭐️
Opening between the vocal chords
Upper Respiratory tract(4)⭐️
-External nose: Air inspiration
-Nasal Cavity: clean & humidify air
-Phaynx: Passageway for food & air
-Larynx: Voice box, airway patent
Lower Respiratory Tract(4)⭐️
-Larynx: Voice box, airway patent
-Trachea: air cleaning tube
-Bronchi: tubes direct air to lungs
-Lungs: network of alveoli and capillaries for gas exchange
Another word for Pharynx⭐️
Throat
Another word for Larynx⭐️
Voice box
Another word for Trachea⭐️
Wind pipe
EC: All 4 blood vessels in pulmonary hilum/root of lung ⭐️
2 pulmonary veins
1 pulmonary artery
1° primary/main bronchus
ToF: If a patient is admitted with pneumonia(infection of lung), it is considered a UPPER respiratory function⭐️
False, lungs are lower
ToF: Inflammation from infection in THROAT, what kind of infection?⭐️
Upper respiratory tract infection
When inhaling air, what element does air contain majority of? ⭐️
(Not oxygen)
Nitrogen (81%)
Oxygen (19%)
The 2 bronchioles and their zone⭐️
Terminal bronchiole(conducting zone)
Respiratory bronchiole (Respiratory / gas exchange zone)
Structures in conducting zone(7)⭐️
Nose, nasal cavity, pharynx, larynx, trachea, bronchi, & terminal bronchiole
Structures in gas exchange zone(2)
Alveoli & respiratory bronchiole
Another word for breathing air into lungs and out⭐️
Pulmonary ventilation
If patient cannot breathe for themself and go into coma, what machine do they need to breathe?⭐️
Ventilator
Another word for gas exchange⭐️
Respiration
If ventilation occurs in between lungs and pulmonary capillaries, what respiration is it?
External respiration (gas exchange)
If ventilation occurs in between tissue capillaries and working tissues, what respiration is it?
Internal respiration
What drives the direction of carbon dioxide & oxygen gases?
Difference in partial pressures
How do we move oxygenated blood back into heart?⭐️
Pulmonary veins
Functions of Respiratory System(5)
-Regulation of blood pH (acidity (7))
-Production of chemical mediators
-Voice Production
-Olfaction
-Protection
ToF: In internal respiration (focus on tissue), Co2 is moving into the tissue⭐️
False, tissue capillary
ToF: In external respiration (lungs), O2 is moving into alveoli⭐️
False, into capillary
3 lines of defense from Respiratory System⭐️
1)Nose hairs
2) Cilia pseudo Stratified w/ goblet cells / Respiratory Epithelium
3)Alveolar macrophages / dust cells
In blood pH acidity, what does 7.35 fall under?
Acidosis
In blood pH acidity, what does 7.45 fall under?
Alkalosis
This forms the roof of the nasal cavity⭐️
Cribiform plate
This portion of the throat is located posterior to the voice box⭐️
Laryngopharyx
This is an “O-shaped” cartilage⭐️
Cricoid cartilage
This is made up of “C-shaped” cartilages⭐️
Trachea
This is NOT a paired cartilage(T)⭐️
Thyroid cartilage
