Chapter 13 Respiratory Review Flashcards
Purpose of the conchae?
Increase surface area, aids in the nasal cavity
Function of the nasal cavity?
Warms, moistens, and filters air
Only external visible part of respiratory system?
Nose including nostrils
Throat?
Pharynx
Voice box
Larynx
Commonly called windpipe? What is it lined with?
Trachea, ciliated mucosa
What does your trachea divide inferiorly?
Right and left bronchus
Three parts of pharynx and location?
Nasopharynx-superior
Oropharynx-middle
Laryngeopharynx-inferior
Three types of tonsils and location?
Pharyngeal-nasopharynx
Palatine-oropharynx
Lingual-base of tongue
Anterior and posterior palate?
Hard palate: anterior
Soft palate: posterior
Empty space between your lungs
Mediastinum
True vocal cords, flaps of mucus membranes
Vocal folds
Located in the larynx, tissue that folds over larynx during swallowing
Epiglottis
Organ located in the respiratory and digestive system?
Pharynx (throat)
What is your Adam’s apple composed of?
Hyaline cartilage
Three functions of the cartilage in the trachea
- stiffens wall to protect airways
- prevent collapsing
- allows for expansion
Four functions of paranasal sinuses
- surrounds nasal cavity
- lighten skull
- enables speech
- mucus
Opening in larynx is called…
Glottis
Right lung has how many lobes? Left lung has how many lobes?
Right-three, left-2
Ciliated epithelium; what do they extend to form?
Bronchi; C-shaped rings
Similar to arterioles, these are regulated by ANS
Bronchioles
Non-respiratory air movements
Coughing, sneezing, crying, laughing, hiccups, yawning
Muscles used in inspiration?
Diaphragm and external muscles
How is gas exchanged in the body?
Diffusion
What does oxygen attach to in order to be used in the body? What does it form,
Attaches to hemoglobin; oxyhemoglobin
What does your pulmonary pleura line? Parietal pleura?
Lungs; thoracic wall
Parts of the respiratory zone?
Respiratory bronchioles
Alveolar ducts
Alveolar sacs
Alveoli
4 stages of respiratory physiology
Pulmonary ventilation
External respiration
Respiratory gas transport
Internal respiration
Amount of air taken in forcibly
=TV+air inhaled
IRV
Amount of air forcibly exhaled after tidal expiration
=TV+air exhaled
ERV
VC=TLC-RV (1200)
TLC=RV+VC
No answer
Yardstick
Air that actually reaches alveoli
=TV-dead space (150)
FV
Smallest part of the respiratory system where gas exchange occurs
Alveoli
